In a recursive IPv6 static route , the route entry has the next-hop router IPv6 address. To configure a recursive IPv6 static route , use the following command format: e. It uses a link state routing LSR algorithm and falls into the group of interior gateway protocols IGPs , operating within a single autonomous system AS.
IS - IS is a link - state routing protocol , operating by reliably flooding link state information throughout a network of routers. Each IS - IS router independently builds a database of the network's topology, aggregating the flooded network information. These addresses are assigned by the IANA and used on public networks.
An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same area identification. A router within an area must maintain a topological database for the area to which it belongs.
The OSPF protocol uses link state routing. On the other hand, BGP protocol uses path vector routing. This address is not included in the routing table and is not defined by the network command.
The address - family command is used to determine which AF will run in the OSPFv3 process, and only one address family can be configured per instance. What may have been the reasoning for removing the network command in OSPFv3? Removing the network statement helps prevent the IPv6 address type errors. The metric keyword and metric-value argument were added. The ipv6 rip default-information command is similar to the default-information originate RIP command, except that it is IPv6-specific.
Originating a default IPv6 route into RIP also forces the advertisement of the route in router updates sent on the interface. The advertisement of the route occurs regardless of whether the route is present in the IPv6 routing table. For example, a user may want to configure one of many routers on a LAN as the preferred default router, so that all default route traffic will transit this router. This function can be achieved by configuring the preferred router to advertise a default route with a lower metric than the other routers on the network.
The ipv6 rip enable interface configuration command is used to enable IPv6 RIP explicitly on required interfaces. In IPv4, the network network-number router configuration command is used to implicitly specify the interfaces on which to run IPv4 RIP. To return the metric to its default value, use the no form of this command.
A number from 1 to When an IPv6 RIP route is received, the interface metric value set by the ipv6 rip metric-offset command is added before the route is inserted into the routing table. Use the ipv6 rip metric-offset command to influence which routes are used, as you prefer. To configure IPv6 Routing Information Protocol RIP to advertise summarized IPv6 addresses on an interface and to specify the IPv6 prefix that identifies the routes to be summarized, use the ipv6 rip summary-address command in interface configuration mode.
To stop the advertising of the summarized IPv6 addresses, use the no form of this command. The ipv6 rip summary-address command is similar to the ip summary-address rip command, except that it is IPv6-specific. Use the ipv6 rip summary-address command to force IPv6 RIP to advertise specific networks on specific interfaces assuming that routes to those networks exist.
If the first bits of the prefix length for a route match the value specified for the ipv6-prefix argument, the prefix specified in the ipv6-prefix argument is advertised instead of the route. As a result, multiple routes can be replaced by a single route whose metric is the lowest metric of the multiple routes.
A route advertisement that is suppressed as a result of split horizon is not considered by RIP when RIP is deciding whether to advertise a summary route. More than one RIP instance is not allowed. To establish static IPv6 routes, use the ipv6 route command in global configuration mode. To remove a previously configured static route, use the no form of this command. The IPv6 network that is the destination of the static route.
Can also be a host name when static host routes are configured. The IPv6 address of the next hop that can be used to reach the specified network. The IPv6 address of the next hop need not be directly connected; recursion is done to find the IPv6 address of the directly connected next hop. When an interface type and interface number are specified, you can optionally specify the IPv6 address of the next hop to which packets are output. You must specify an interface type and an interface number when using a link-local address as the next hop the link-local next hop must also be an adjacent device.
Interface type. For more information about supported interface types, use the question mark? You can use the interface-type argument to direct static routes out point-to-point interfaces such as serial or tunnel interfaces and broadcast interfaces such as Ethernet interfaces. When using the interface-type argument with point-to-point interfaces, there is no need to specify the IPv6 address of the next hop.
When using the interface-type argument with broadcast interfaces, you should always specify the IPv6 address of the next hop or ensure that the specified prefix is assigned to the link. A link-local address should be specified as the next hop for broadcast interfaces. Interface number. For more information about the numbering syntax for supported interface types, use the question mark?
Optional An administrative distance. The default value is 1, which gives static routes precedence over any other type of route except connected routes. Optional Tag value that can be used as a "match" value for controlling redistribution via route maps. The optional ipv6-address argument was added. The optional unicast and multicast keywords and administrative-multicast-distance argument were added. The optional vrf and nexthop-vrf keywords, and vrf-name and next-hop-address arguments were added.
The name name keyword and argument were added. Use the ipv6 route command to implement static multicast routes in IPv6. For a static multicast route, the IPv6 address of the next-hop device must be provided.
The administrative-multicast-distance argument determines the distance that will be used when selecting this route for RPF. When the unicast keyword is used, this route will not be used in multicast RPF selection. When the ipv6 route command is used with the multicast keyword, the route will not be populated in the unicast RIB.
When the optional administrative-multicast-distance argument is not specified, the multicast RPF administrative distance defaults to the same value as that determined by the administrative-distance argument. The following example shows a static route used for both unicast routing and multicast RPF selection:. The following example shows a static route used for both unicast routing and multicast RPF selection, but with different administrative distances:.
The following example configures a static default route within a VRF. Use of the global keyword in this static route provides access to the Internet:.
To assign a high-priority tag to an integrated Intermediate System-to-Intermediate System IS-IS IPv6 prefix to be used for controlling redistribution via route maps, use the ipv6 route priority high command in address family configuration mode. To remove the IPv6 prefix priority, use the no form of this command. Assigns a tag value that can be used as a match value for controlling redistribution via route maps.
The range is from 1 to To specify static route Bidirectional Forwarding Detection for IPv6 BFDv6 neighbors, use the ipv6 route static bfd command in global configuration mode. To remove a static route BFDv6 neighbor, use the no form of this command. Optional Name of the virtual routing and forwarding VRF instance by which static routes should be specified.
Use the ipv6 route static bfd command to specify static route neighbors. All of the static routes that have the same interface and gateway specified in the configuration share the same BFDv6 session for reachability notification.
Therefore, this command must be configured on each endpoint router. An IPv6 static BFDv6 neighbor must be fully specified with the interface and the neighbor address and must be directly attached. All static routes that specify the same values for vrf vrf-name , interface-type interface-number , and ipv6-address will automatically use BFDv6 to determine gateway reachability and take advantage of fast failure detection.
To allow a recursive IPv6 static route to resolve using the default IPv6 static route, use the ipv6 route static resolve default command in global configuration mode. To remove this function, use the no form of this command. Recursive IPv6 static routes do not resolve via the default route. The ipv6 route static resolve default command restores legacy behavior and allows resolution using the default route. The following example enables an IPv6 recursive static route to be resolved using a IPv6 static default route:.
To place the router in router configuration mode, create an Enhanced Interior Gateway Routing Protocol EIGRP routing process in IPv6, and configure this process, use the ipv6 router eigrp command in global configurationmode. To shut down a routing process, use the no form of this command.
The event-log-size value is the memory allocation, in bytes, calculated dynamically based on available memory. The event-log-size value is between 0 and the dynamically calculated number. The eigrp event-log-size keyword and event-log-size argument were added. Use the ipv6 router eigrp command in global configuration mode to place the router in router configuration mode and create a routing process.
To configure an Intermediate System-to-Intermediate System IS-IS routing process for IPv6 on an interface and to attach an area designator to the routing process, use the ipv6 router isis command in interface configuration mode. Meaningful name for a routing process. If a name is not specified, a null name is assumed and the process is referenced with a null name. Required for multiarea IS-IS configuration. Each area in a multiarea configuration should have a nonnull area name to facilitate identification of the area.
Optional for conventional IS-IS configuration. Before the IPv6 IS-IS routing process can be configured, IPv6 routing must be enabled using the ipv6 unicast-routing global configuration command, and an IPv6 address must be configured on an interface using either the ipv6 enable interface configuration command or the the ipv6 address interface configuration command.
The ipv6 enable command will automatically configure an IPv6 link-local address on the interface. Configures an IPv6 link-local address for an interface and enables IPv6 processing on the interface. Enables an interface for IPv6 processing and automatically assigns an IPv6 link-local address on the interface.
To enable the network mobility NEMO routing process on the home agent and place the router in router configuration mode, use the ipv6 router nemo command in global configuration mode.
To disable this function, use the no form of the command. The NEMO routing process is not enabled on the home agent. This command enables the NEMO routing process on the home agent. In the following example, NEMO is enabled on the home agent:. Internal identification. It is locally assigned and can be a positive integer from 1 to Skip to content Skip to search Skip to footer.
