Configuration procedure
1. Configure IPv6 addresses for interfaces on the switches and enable IPv6 IS-IS. (Details not
shown.)
2. Configure IPv6 IS-IS on the switches to make sure Switch A, Switch B, and Switch C can
communicate with each other at Layer 3. (Details not shown.)
3. Configure IPv6 IS-IS FRR:
Enable IPv6 IS-IS FRR to calculate a backup next hop through LFA calculation, or designate a
backup next hop by using a referenced routing policy.
 (Method 1.) Enable IPv6 IS-IS FRR to calculate a backup next hop through LFA calculation:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] isis 1
[SwitchA-isis-1] address-family ipv6
[SwitchA-isis-1-ipv6] fast-reroute lfa
# Configure Switch B.
<SwitchB> system-view
[SwitchB] isis 1
