BFD for IPv6 IS-IS configuration example
Network requirements
As shown in Figure 98 :
• 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.

Device Interface IPv6 address
Switch A Vlan-int10 2001::1/64
Switch A Vlan-int11 2001:2::1/64
Switch B Vlan-int10 2001::2/64
Switch B Vlan-int13 2001:3::2/64
Switch C Vlan-int11 2001:2::2/64
Switch C Vlan-int13 2001:3::1/64
Configuration procedure
1. Configure IPv6 addresses for interfaces. (Details not shown.)
2. Configure IPv6 IS-IS:
# Configure Switch A.
<SwitchA> 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
