Configuring BFD for IPv6 IS-IS
Bidirectional forwarding detection (BFD) can quickly detect faults between IPv6 IS-IS neighbors to
improve the convergence speed of IPv6 IS-IS. For more information about BFD, see High Availability
Configuration Guide.
To configure BFD for IPv6 IS-IS:
Step
1.
Enter system view.
2.
Enable an IS-IS process and
enter IS-IS view.
3.
Configure the NET for the
IS-IS process.
4.
Enter IPv6 address family
view.
5.
Return to system view.
6.
Enter interface view.
7.
Enable IPv6 for IS-IS on the
interface.
8.
Enable BFD for IPv6 IS-IS.
Configuring IPv6 IS-IS FRR
IMPORTANT:
ECMP routes do not support FRR.
A link or router failure on a path can cause packet loss and routing loop. IPv6 IS-IS FRR enables fast
rerouting to minimize the failover time.
