IPv6: RIPng VRF-Aware Support

IPv6: RIPng VRF-Aware Support

The IPv6: RIPng VRF-Aware Support feature enables the availability of separate routing tables for every provider edge-customer edge (PE-CE) scenario thus allowing improved routes protection, modularity, and potential reduction in the size of the routing table.

This module explains how to configure the IPv6: RIPng VRF-Aware Support feature.

Information About IPv6: RIPng VRF-Aware Support

IPv6 Routing: RIP for IPv6

IPv6 RIP functions the same and offers the same benefits as RIP in IPv4. RIP enhancements for IPv6, detailed in RFC 2080, include support for IPv6 addresses and prefixes, and the use of the all-RIP-devices multicast group address FF02::9 as the destination address for RIP update messages.

IPv6: RIPng VRF-Aware Support

When not in VRF mode, every IPv6 Routing Information Protocol (RIP)—also know as RIP Next Generation (RIPng)—process and the configuration associated with it, keeps all the routes in the same routing table. As in other routing protocols, it is often required to keep the protocol-related routes stored in separate routing tables. The IPv6: RIPng VRF-Aware Support feature enables isolation, modularity, and potential performance improvement by reducing the number of routes stored in a single routing table.

The IPv6: RIPng VRF-aware Support feature enables the network administrator to create different RIP routing tables and lets the network administrator share the same protocol configuration stored in a single RIP protocol configuration block.

    Step 9 interface type number


    Example:
    Device (config)# interface Ethernet 0/0
     

    Specifies the interface type and number, and enters interface configuration mode.

     
    Step 10 ipv6 rip vrf-name enable


    Example:
    Device(config-if)# ipv6 rip vrf1 enable
     

    Enables an IPv6 RIP routing process on the interface.

     
    Step 11 end


    Example:
    Device (config)# end
     

    Exits interface configuration mode and returns to privileged EXEC mode.

     
    Step 12 debug ipv6 rip vrf vrf-name


    Example:
    Device# debug ipv6 vrf vrf1
     

    Displays debugging information related to VRF support for the specified VRF IPv6 RIP.

     
    Step 13 show ipv6 rip vrf vrf-name next-hops


    Example:
    Device# show ipv6 vrf vrf1 next-hop
     

    Displays the next hops in the specified VRF RIPng routing table.

     
    Step 14 show ipv6 rip vrf vrf-name database


    Example:
    Device# show ipv6 vrf vrf1 database
     

    Displays the associated RIP local Routing Information Base (RIB).

     

    Configuring Examples for IPv6: RIPng VRF-Aware Support

    Example: Configuring IPv6: RIPng VRF-Aware Support

    The following is a sample configuration of the IPv6: RIPng VRF-Aware Support feature.

    Device> enable
    Device# configure terminal 
    Device(config)# ipv6 unicast-routing
    Device(config)# vrf definition vrf1 
    Device(config-vrf)# address-family ipv6
    Device(config-vrf-af)# exit
    Device(config-vrf)# exit
    Device(config)# ipv6 rip vrf-mode enable 
    Device(config)# interface Ethernet 0/0
    Device(config-if)# ipv6 rip vrf1 enable 
    Device(config-if)# end
    
    

    Example: Verifying IPv6: RIPng VRF-Aware Support

    The following is sample output from the debug ipv6 rip vrf command.

    Device> debug ipv6 rip vrf myRIP
    
    RIP Routing Protocol debugging is on for vrf myRIP
    

    The following is sample output from the show ipv6 rip vrf database command.

    Device> show ipv6 rip vrf myRIP database
    
    RIP VRF "myRIP", local RIB
    

    The following is sample output from the show ipv6 rip vrf next-hops command.

    Device> show ipv6 rip vrf myRIP next-hops
    
    RIP VRF "myRIP", Next Hops

    IPv6: RIPng VRF-Aware Support

    Cisco IOS XE Release 3.9S

    IPv6 Routing Information RIP, also known as RIP Next Generation (RIPng), when not VRF aware, works only with routes that are available in the default global routing table. But RIPng, when operating in VRF mode instead, creates a separate routing table for each VRF. IPv6: RIPng VRF-Aware Support feature enables the availability of separate routing tables for every provider edge-customer edge (PE-CE) scenario thus allowing improved routes protection, modularity and potential reduction in the size of the routing table.

    The following commands were introduced or modified: clear ipv6 rip, , debug ipv6 rip , ipv6 rip vrf-mode enable and show ipv6 rip.
