4. Configure preferred values so Link B is used to forward traffic between Router A and Router D:
# Configure Router A to set the preferred value to 100 for routes received from Router B.
[RouterA-bgp-ipv6] peer 3001::2 preferred-value 100
[RouterA-bgp-ipv6] quit
[RouterA-bgp] quit
# Configure Router D to set the preferred value to 100 for routes received from Router B.
[RouterD-bgp-ipv6] peer 3002::1 preferred-value 100
[RouterD-bgp-ipv6] quit
[RouterD-bgp] quit
5. Configure BGP FRR:
# On Router A, create routing policy frr to set a backup next hop 2001::2 (Router C) for the route
destined for 4::/64.
<RouterA> system-view
[RouterA] ipv6 prefix-list abc index 10 permit 4:: 64
[RouterA] route-policy frr permit node 10
[RouterA-route-policy] if-match ipv6 address prefix-list abc
[RouterA-route-policy] apply ipv6 fast-reroute backup-nexthop 2001::2
[RouterA-route-policy] quit
# Apply the routing policy to BGP FRR for BGP IPv6 unicast address family.
[RouterA] bgp 100
[RouterA-bgp] address-family ipv6 unicast
[RouterA-bgp-ipv6] fast-reroute route-policy frr
[RouterA-bgp-ipv6] quit
[RouterA-bgp] quit
# On Router D, create routing policy frr to set a backup next hop 2002::1 (Router C) for the route
destined for 1::/64.
<RouterD> system-view
[RouterD] ipv6 prefix-list abc index 10 permit 1:: 64
[RouterD] route-policy frr permit node 10
[RouterD-route-policy] if-match ipv6 address prefix-list abc
[RouterD-route-policy] apply ipv6 fast-reroute backup-nexthop 2002::1
[RouterD-route-policy] quit
# Apply the routing policy to BGP FRR for BGP IPv6 unicast address family.
[RouterD] bgp 200
[RouterD-bgp] address-family ipv6 unicast
[RouterD-bgp-ipv6] fast-reroute route-policy frr
[RouterD-bgp-ipv6] quit
[RouterD-bgp] quit
Verifying the configuration
# Display detailed information about the route to 4::/64 on Router A. The output shows the backup next
hop for the route.
