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
To enable the IPv6 ND proxy feature for the node:
R2>#en
No password has been assigned yet...
R2#conf t
R2(config)# ipv6 nd proxy
R2(config)#
