Configuration procedure
Configure IP addresses for the interfaces on each router and configure IS-IS.
1.
Follow
(Details not shown.)
Configure IS-IS on the routers, ensuring that Router A, Router D, and Router S can
communicate with each other at Layer 3. (Details not shown.)
Configure IS-IS FRR:
2.
Enable IS-IS FRR to either automatically calculate a backup next hop, or designate a backup
next hop by using a routing policy.
Method 1: Enable IS-IS FRR to automatically calculate a backup next hop.
# Configure Router S.
<RouterS> system-view
[RouterS] bfd echo-source-ip 1.1.1.1
[RouterS] isis 1
[RouterS-isis-1] fast-reroute auto
[RouterS-isis-1] quit
# Configure Router D.
<RouterD> system-view
[RouterD] bfd echo-source-ip 4.4.4.4
[RouterD] isis 1
[RouterD-isis-1] fast-reroute auto
[RouterD-isis-1] quit
Method 2: Enable IS-IS FRR to designate a backup next hop by using a routing policy.
# Configure Router S.
<RouterS> system-view
[RouterS] bfd echo-source-ip 1.1.1.1
[RouterS] ip ip-prefix abc index 10 permit 4.4.4.4 32
[RouterS] route-policy frr permit node 10
[RouterS-route-policy] if-match ip-prefix abc
[RouterS-route-policy] apply fast-reroute backup-interface gigabitethernet 2/1/1
backup-nexthop 12.12.12.2
[RouterS-route-policy] quit
[RouterS] isis 1
[RouterS-isis-1] fast-reroute route-policy frr
[RouterS-isis-1] quit
# Configure Router D.
<RouterD> system-view
