published: 5th of February 2019

Overview

4 steps to configure RIPv2.

Define a RIP group
Assign interfaces to the RIP group
Define a routing policy to export routes
Assign the routing policy to the RIP group

Configuration

Define a RIP group.

    cmd
  
    set protocols rip group RIP-GROUP

Assign interfaces to the RIP group.

    cmd
  
    set protocols rip group RIP-GROUP neighbor ge-0/0/2.0

Define a routing policy to export routes.

    cmd
  
    set policy-options policy-statement EXPORT-RIP term 1 from protocol direct
set policy-options policy-statement EXPORT-RIP term 1 from protocol rip
set policy-options policy-statement EXPORT-RIP term 1 then accept

Assign the routing policy to the RIP group.

    cmd
  
    set protocols rip group RIP-GROUP export EXPORT-RIP

Topology

P1R1

    cmd
  

    set protocols rip group RIP-GROUP
set protocols rip group RIP-GROUP neighbor ge-0/0/2.0
set policy-options policy-statement EXPORT-RIP term 1 from protocol direct
set policy-options policy-statement EXPORT-RIP term 1 from protocol rip
set policy-options policy-statement EXPORT-RIP term 1 then accept
set protocols rip group RIP-GROUP export EXPORT-RIP
  

P1R2

    cmd
  

    set protocols rip group RIP-GROUP
set protocols rip group RIP-GROUP neighbor ge-0/0/1.0
set policy-options policy-statement EXPORT-RIP term 1 from protocol direct
set policy-options policy-statement EXPORT-RIP term 1 from protocol rip
set policy-options policy-statement EXPORT-RIP term 1 then accept
set protocols rip group RIP-GROUP export EXPORT-RIP
  

Verification

Show RIP neighbors.

    cmd
  
    show rip neighbor
