Configuration Roadmap
The configuration roadmap is as follows:
1. Enable IPv6 forwarding capability on the router.
2. Configure the link-local unicast address on Ethernet 1/0/0.
3. Enable the routers to send RA messages on Ethernet 1/0/0.
Data Preparation
To complete the configuration, you need the following data:
l IPv6 link-local address for an interface.
Procedure
Step 1 Enable the IPv6 forwarding capability on the routers.
# Configure RouterA.
<Huawei> system-view
[Huawei] sysname RouterA
[RouterA] ipv6
# Configure RouterB.
<Huawei> system-view
[Huawei] sysname RouterB
[RouterB] ipv6
Step 2 Configure the link-local unicast address.
# Configure RouterA.
[RouterA] interface ethernet 1/0/0
[RouterA-Ethernet1/0/0] ipv6 enable
[RouterA-Ethernet1/0/0] ipv6 address auto link-local
# Configure RouterB.
[RouterB] interface ethernet 1/0/0
[RouterB-Ethernet1/0/0] ipv6 enable
[RouterB-Ethernet1/0/0] ipv6 address auto link-local
Step 3 Enable the routers to send RA messages.
# Enable RouterA to send RA messages.
[RouterA] interface ethernet 1/0/0
[RouterA-Ethernet1/0/0] undo ipv6 nd ra halt
# Enable RouterB to send RA messages.
