Configuring RIP on Juniper M20 / M40 router
In this tutorial:
Configure RIP on Juniper.
Configure routing policy for
RIP routes to transit through Juniper router.
View routes learned on Cisco
and Juniper.
Topology:
Configuration on JunOS
#Step 1 : Host name for Juniper M40
set system host-name JunOS
#Step 2 : interface ip address
set interface lo0.0 family inet address 2.2.2.2/32
set interface em0.0 family inet address 10.1.2.2/24
set interface em1.0 family inet address 10.2.3.2/24
#Step 3 : Create policy to transit RIP routes through JunOS
edit policy-options policy-statement RIP_ROUTE
set term RIP_TRANS_ROUTE from protocol rip
set term RIP_TRANS_ROUTE then accept
set term DIRECT from protocol direct
set term DIRECT then accept
#Step 4 : RIP configuration on JunOS
edit protocol rip group NEIGHBOURS
set export RIP_ROUTE
set neighbor em0.0
set neighbor em1.0
top
#Step 5 : Commit changes
commit
Show configuration on JunOS

Information above is either from RFCs or it's Googled. This blog is result of my enthusiasm, desire and hard work to lean networking and share my leanings. Most of the times I’ll be using GNS3 network simulator. All I've here is collection of my findings, thanks to Google. Please do not ask for any of the software from CISCO/Juniper, it's better to Google it and try your luck.
