Usage Guidelines

Usage Scenario

If two hosts physically belong to different network segments and no gateway is configured, run the ipv6 nd proxy enable command on the VBDIF interface of the device that connects the two hosts. This command enables routed proxy ND, which parses IPv6 addresses between the hosts.

Prerequisites

IPv6 has been enabled in the VBDIF interface view using the ipv6 enable command.

Precautions

After routed proxy ND is configured on an interface, the device counts the number of received NS unicast packets twice. As a result, the number of NS packets displayed in the display cpu-defend statistics packet-type nd command output may be greater than the actual number of NS packets sent to the CPU.

Example
