Configuring Local ND Proxy on an interface

IPv6 ND Proxy can be used to configure individual interfaces on a router.
  1. Enter global configuration mode.
    Router# configure terminal
  2. Specify the interface to be configured in interface configuration mode.
    Router(config)# interface ethernet 1/1/3
  3. Enable IPv6 routing for the interface. The ipv6 enable command configures a router interface with an automatically computed link-local address.
    Router(config-if-e1000-1/1/3)# ipv6 enable
  4. Enable IPv6 ND Proxy using the ipv6 nd local-proxy command.
    Router(config-if-e1000-1/1/3)# ipv6 nd local-proxy
  5. Use the show ipv6 neighbor proxy command to display host entries for which the router acts as the proxy.
    Router(config)# show ipv6 neighbor proxy
              
              Neighbor Entries in VRF: default-vrf
    IPv6 Address                            LinkLayer-Addr State           Age        Port               vlan  IsR
    4:1:1::100                              609c.9f52.241c REACH           31         e 1/1/25           1     1
    4:1:1::99                               609c.9f52.f20d REACH           31         e 1/1/25           1     1
    
     

The following example configures IPv6 ND Proxy on the ethernet interface 1/1/3. The interface is manually configured with a link-local address.

Router# configure terminal
Router(config)# interface ethernet 1/1/3
Router(config-if-e1000-1/1/3)# ipv6 address FE80::240:D0FF:FE48:4672 link-local
Router(config-if-e1000-1/1/3)# ipv6 nd proxy
