Configuring Proxy Neighbor Advertisements

Much like proxy ARP, proxy Neighbor Discovery is a means by which one interface responds to a Neighbor Discovery query on behalf of another interface.

To configure proxy Neighbor Discovery:

  1. Access an IPv6 interface.
    host1(config)#interface fastEthernet 0/0 host1(config-if)#
  2. Enable Neighbor Discovery on the current interface.
    host1(config-if)#ipv6 nd

    Note: This command is redundant when configuring Neighbor Discovery over Ethernet, because neighbor solicitations and advertisements are automatically sent on Ethernet interfaces.

  3. Enable IPv6 neighbor proxy.
    host1(config-if)#ipv6 nd proxy
