BFD for IPv6 IS-IS configuration example
683B
Network requirements
• As shown in
1238H
Figure 85 , configure IPv6 IS-IS on Switch A and Switch B so that they can reach other.
• Enable BFD on VLAN-interface 10 of Switch A and Switch B. After the link between Switch B and
the Layer-2 switch fails, BFD can quickly detect the failure and notify IPv6 IS-IS of the failure. Then
Switch A and Switch B communicate through Switch C.

Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. Configure IPv6 IS-IS:
# Configure Switch A.
system-view
[SwitchA] isis 1
[SwitchA-isis-1] is-level level-1
[SwitchA-isis-1] network-entity 10.0000.0000.0001.00
[SwitchA-isis-1] ipv6 enable
[SwitchA-isis-1] quit
[SwitchA] interface vlan-interface 10
[SwitchA-Vlan-interface10] isis ipv6 enable 1
[SwitchA-Vlan-interface10] quit
[SwitchA] interface vlan-interface 11
[SwitchA-Vlan-interface11] isis ipv6 enable 1
[SwitchA-Vlan-interface11] quit
# Configure Switch B.
