    Monitoring Available IPv6 Routes for Reverse-Path Forwarding

    Purpose

    Display the IPv6 routes that the router can use for RPF. You can specify the IPv6 address and the network mask to view routes to a particular destination. You can use the detail keyword to view more detailed information about routes to a particular destination. You can specify a unicast routing protocol to view routes associated with that protocol.

    Action

    To display all IPv6 routes that the router can use for RPF:

    host1#show ipv6 rpf-route 
    Protocol/Route type codes:
      O- OSPF, E1- external type 1, E2- external type2,
      N1- NSSA external type1, N2- NSSA external type2
      L- MPLS label, V- VR/VRF, *- indirect next-hop
             Prefix/Length             Type    Dst/Met         Intf        
    -------------------------------- --------- ------- --------------------
    11:1:1:10::/60                   Static    1/0     ATM2/0.300          
    21:2:2:20::/60                   Static    1/0     ATM2/0.300          
    31:2:2:20::/60                   Connect   0/0     ATM2/0.300          
    131:1:1:10::/60                  Connect   0/0     ATM2/1.1300         
    1000::/64                        Static    1/0     ATM2/0.300         

    To display more detailed information about an IPv6 route to a particular destination:

    host1#show ipv6 rpf-route 1000::/64 detail
    
    1000::/64 Type:Static  Distance:1  Metric:0
            NextHop:31:2:2:23::2:3  IntfIndex 18  Intf ATM2/0.300

    Meaning

    Table 1 lists the show ipv6 rpf-route command output fields.
