R3102-R3103-HP 6600/HSR6600 Routers Layer 3 - IP Routing Configuration Guide

Configuring RIP FRR

Network requirements

As shown in Figure 11, Router S, Router A, and Router D run RIPv2. Configure RIP FRR so that when Link

A fails, traffic can be switched to Link B immediately.

Figure 11 Network diagram

Configuration procedure

1. Configure IP addresses for the interfaces on each router and configure RIPv2:

Follow Figure 11 to c

onfigure the IP address and subnet mask of each interface on the routers.

(Details not shown.)

Configure RIPv2 on the routers, ensuring that Router A, Router D, and Router S can communicate

with each other at Layer 3. (Details not shown.)

2. Configure RIP FRR:

# 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

backup-nexthop 12.12.12.2

[RouterS-route-policy] quit

[RouterS] rip 1

[RouterS-rip-1] fast-reroute route-policy frr

[RouterS-rip-1] quit

# Configure Router D.

<RouterD> system-view

[RouterD] bfd echo-source-ip 4.4.4.4

[RouterD] ip ip-prefix abc index 10 permit 1.1.1.1 32

[RouterD] route-policy frr permit node 10

[RouterD-route-policy] if-match ip-prefix abc

[RouterD-route-policy] apply fast-reroute backup-interface GigabitEthernet 2/1/1

backup-nexthop 24.24.24.2

[RouterD-route-policy] quit

[RouterD] rip 1

[RouterD-rip-1] fast-reroute route-policy frr

[RouterD-rip-1] quit
