IPv6 Neighbor Discovery Proxy
This feature provides support for proxying the IPv6 Neighbor Discovery (ND) protocol to allow the forwarding of the following ICMP messages between upstream and downstream interfaces:
l Router Advertisement (RA) l Neighbor Solicitation (NS) l Neighbor Advertisement (NA) l Router Solicitation (RS) l Redirect
The Neighbor Discovery (ND) protocol is used to discover the Link Layer address of IPv6 destinations. In IPv4, this is achieved by using ARP.
Configure ND Proxy in the CLI using the following syntax:
config system nd-proxy set status {enable|disable}
set member <interface> <interface> [<interface>…] end
| Option | Description |
| status | Enable/disable the use of neighbor discovery proxy |
| member | List of interfaces using the neighbor discovery proxy |
An example of a configuration can be found in the IPv6 Configuration section under IPv6 Neighbor Discovery Proxy on page 164
