Solution
The configuration for the IPv6 version of RIP, called RIPng, is basically the same as
for the IPv4 version of RIP. RIPng has a separate configuration hierarchy:
[edit protocols ripng]
aviva@RouterH# set group v6-rip-group neighbor t1-4/0/0.0
aviva@RouterH# set group v6-rip-group neighbor fe-1/0/1.0
You also need to configure the interfaces to support IPv6 traffic:
[edit interfaces]
aviva@RouterH# set t1-r/0/0 unit 0 family inet6
aviva@RouterH# set fe-1/0/1 unit 0 family inet6
To have the router advertise RIPng routes to its neighbors, configure a routing policy
and apply it to the RIPng group:
[edit policy-options]
aviva@RouterH# set policy-statement advertise-rip-routes term 1 from protocol direct
aviva@RouterH# set policy-statement advertise-rip-routes term 1 from protocol rip
aviva@RouterH# set policy-statement advertise-rip-routes term 1 then accept
[edit protocols ripng]
aviva@RouterH# set group v6-rip-group neighbor export advertise-rip-routes

JUNOS RIPng configuration for IPv6 networks is almost identical to the IPv4 RIP configure
configuration. You configure the protocol with set ripng commands instead of
set rip commands and use show ripng commands instead of show rip commands to
check the RIP status. Also, make sure to set the IPv6 address with the inet6 family
on the interfaces running RIPng and on the loopback interface, lo0.
To have RIPng advertise its RIPng routes, you create a routing policy as you did with
RIPv4. This recipe uses the same policy configured in Recipe 10.2.
To check that the RIPng configuration is working and the router knows about its
neighbors, use the show ripng neighbor command:
aviva@RouterG> show ripng neighbor
Source Dest In

-------- ----- ------- ------- ---- ---- ---
fe-1/0/1.0 Up fe80::205:85ff:fec2:2ef5 ff02::9 yes yes 1
t1-4/0/0.0 Up fe80::205:85ff:fec2:2ed0 ff02::9 yes yes 1
This output shows the two configured RIPng interfaces. The first column shows the
interface that connects to the neighbor, and the second column shows that the neighbor
is operational, or Up, and is listening to RIPng traffic. The Send and Recv columns
indicate that the router is both sending RIPng packets to and receiving packets from
its neighbors. The last column shows the inbound metric, which is how many hops
away the neighbor is. Here, each neighbor is directly connected and is one hop away,
