Syntax [no]local-proxy-nd
Context configure>service>ies>interface>ipv6
Description This command enables or disables neighbor discovery on the interface.
When enabled, the ISAM will behave as follows:
• Respond to all neighbor solicitation messages received on the IP interface for IPv6
addresses in the subnet(s) with the system MAC address as link layer address, provided
the link layer address of the destination/target IP address was learned and thus available
in the ISAM’s neighbor cache.
• Forward IPv6 traffic between hosts in the subnet(s) of the IP interface.
• Drop IPv6 traffic between hosts if the link layer address information for the IPv6 destination
has not been learned.
