Usage Scenario

When a device is connected to a host, it periodically sends RA packets to the host. An RA packet carries the IPv6 address prefix and flag information of stateful autoconfiguration. You can run the undo ipv6 nd ra halt command to enable the device to send RA packets.
When a device is connected to another device, that is, there is no host on the network, sending RA packets is not required. The default configuration is recommended.

 Root Cause

Comfiguration miss with "undo ipv6 nd ra halt"


Add bellow command under interface:

interface GigabitEthernet0/0/0
undo portswitch
ipv6 enable
ipv6 address 2405:6400:46:2002::1/51
dhcpv6 server tv
undo ipv6 nd ra halt
