published: 7th of February 2019

Overview

4 steps to configure RIPng.

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

Configuration

Define a RIPng group.

    cmd
  
    set protocols ripng group RIPNG-GROUP

Assign interfaces to the RIPng group.

    cmd
  
    set protocols ripng group RIPNG-GROUP neighbor ge-0/0/2.0

Define a routing policy to export routes.

    cmd
  
    set policy-options policy-statement EXPORT-RIPNG term 1 from protocol direct
set policy-options policy-statement EXPORT-RIPNG term 1 from protocol ripng
set policy-options policy-statement EXPORT-RIPNG term 1 then accept

Assign the routing policy to the RIPng group.

    cmd
  
    set protocols ripng group RIPNG-GROUP export EXPORT-RIPNG

Topology

P1R1

    cmd
  

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

P1R2

    cmd
  

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

Verification

Show RIPng neighbors.

    cmd
  
    show ripng neighbor
