ipv6 nd proxy
Congures a single IPv6 subnet prex to support multiple physical links in IPv6 Neighbor Discovery.
Syntax
ipv6 nd proxy
no ipv6 nd proxy
Command Default
This feature is disabled.
Modes
The ipv6 nd proxy is congurable under the global conguration mode.
Usage Guidelines
The IPv6 ND proxy command turns on the IPv6 ND proxy capability for the node, and is run at the
conguration level.
Use the no form of this command to remove the ND proxy conguration.
Per RFC 4389, ND proxy can be used to bridge multiple links into a single entity to simplify management, as there is no need
to allocate subnet numbers to the dierent networks. This can help alleviate the need to congure NAT in IPv6 networks.
NOTE
This is an IETF Experimental Protocol. It is the responsibility of the user to ensure that appropriate network-layer
support is provided.
The following limitations apply:
The ipv6 nd proxy is not supported over v6 tunnel interface.
The IPv6 nd proxy programs the RACL to force the Unicast NS, sent during neighbor refresh, to the CPU for
processing as proxy NS.
The ipv6 nd proxy is currently supported for NS and NA messages and are not supported for other ND messages
like RS, RA and redirect message.
The IPv6 nd proxy is not supported for the IPsec tunnels and on MCT.
Examples
