IPv6 uRPF configuration example for interfaces

As shown in Figure 216, perform the following tasks:

• Configure strict IPv6 uRPF check on GigabitEthernet 1/0/1 of Router B and permit packets from network 1010::/64.

• Configure strict IPv6 uRPF check on GigabitEthernet 1/0/1 of Router A and allow using the default route for IPv6 uRPF check.

  Figure 211: Network diagram

  

1. Configure Router B:

   # Configure IPv6 ACL 2010 to permit traffic from network 1010::/64.

   <RouterB> system-view
   [RouterB] acl ipv6 basic 2010
   [RouterB-acl-ipv6-basic-2010] rule permit source 1010:: 64
   [RouterB-acl-ipv6-basic-2010] quit
   

   # Specify an IPv6 address for GigabitEthernet 1/0/1.

   [RouterB] interface gigabitethernet 1/0/1
   [RouterB-GigabitEthernet1/0/1] ipv6 address 1000::2/64
   

   # Configure strict uRPF check on GigabitEthernet 1/0/1.

   [RouterB-GigabitEthernet1/0/1] ipv6 urpf strict acl 2010
   

2. Configure Router A:

   # Specify an IPv6 address for GigabitEthernet 1/0/1.

   <RouterA> system-view
   [RouterA] interface gigabitethernet 1/0/1
   [RouterA-GigabitEthernet1/0/1] ipv6 address 1000::1/64
   

   # Configure strict uRPF check on GigabitEthernet 1/0/1 and allow using the default route for IPv6 uRPF check.

   [RouterA-GigabitEthernet1/0/1] ipv6 urpf strict allow-default-route
