Enabling The Dhcpv6 Relay Agent To Advertise Ipv6 Prefixes; Display And Maintenance Commands For Dhcpv6 Relay Agent - H3C SR8800-F Configuration Manual

Enabling the DHCPv6 relay agent to advertise
IPv6 prefixes
A DHCPv6 client can obtain an IPv6 prefix through DHCPv6 and use this IPv6 prefix to assign IPv6
address to clients in a downstream network. If the IPv6 prefix is in a different subnet than the IPv6
address of the DHCPv6 client's upstream interface, the clients in the downstream network cannot
access the external network. You can enable the DHCPv6 relay agent that is on the same link as the
DHCPv6 client to advertise the IPv6 prefix.
To enable the DHCPv6 relay agent to advertise IPv6 prefixes:
Step
1. Enter system view.
2. Enable the DHCPv6 relay
agent to advertise IPv6
prefixes.

Remarks
N/A
By default, the DHCPv6 relay
agent does not advertise IPv6
prefixes.
Before using this command, make
sure the DHCPv6 relay agent is
enabled to record DHCPv6 relay
entries.
