Usage Guidelines

Usage Scenario

To allow the device to send RA packets that carry unicast destination IP addresses when assigning IPv6 addresses or prefixes to IPoEv6 access users, run the ipv6 nd ra unicast command in the BAS interface view.

Configuration Impact

After the ipv6 nd ra unicast command is run, the device uses the source IP address in a user's ND or DHCPv6 packet as the destination IP address in an RA packet.

Precautions

The ipv6 nd ra unicast command in the BAS interface view applies only to IPoEv6 users.

Example

# Configure the destination IP addresses in RA packets as unicast addresses in the BAS interface view.
