Juniper RIP OSPF Routes Redistribution


IN FIGURE 1 WE SHOW A TOPOLOGY THAT IS RUNNING OSPF AND RIP. THIS LAB IS DESIGNED ON VMWARE JUNIPER OLIVE. THE GOAL FOR THIS TOPOLOGY IS SIMPLE: ROUTES REDISTRIBUTION BETWEEN ROUTERS. SO LET'S START:  


1 Configuration on Juniper 1

1.1 Configure RIP protocol:

[edit]
root@juniper1# set interface em0.0 family inet address 192.168.3.1/24
root@juniper1# set interface em1.0 family inet address 10.1.1.5/24 ('this interface is used for test purposes)
root@juniper1# set protocols rip group small-rip neighbor em0.0

1.2 Configure RIP policy:

Default policy of RIP is to send out no routes unless explicitly told to do so. In order to begin sending out routes, first write a policy on Juniper 1 that sends the locally connected interface routes into RIP:

[edit]
root@juniper1# set policy-options policy-statement send-connected term 1 from protocol direct
root@juniper1# set policy-options policy-statement send-connected then accept

1.3 Apply the policy to RIP:

[edit]
root@juniper1# set protocols rip group small-rip export send-connected

2 Configuration on Juniper 2:

2.1 Configure RIP protocol on interface em1:

[edit]
root@juniper2# set interface em0.0 family inet address 192.168.1.2/24
root@juniper2# set interface em1.0 family inet address 192.168.3.2/24
root@juniper2# set protocols rip group small-rip neighbor em1.0

2.2 Configure RIP policy:

root@juniper2# set policy-options policy-statement send-connected term 1 from protocol direct
root@juniper2# set policy-options policy-statement send-connected then accept

2.3 Apply the policy to RIP:

[edit]
root@juniper2# set protocols rip group small-rip export send-connected

2.4 Configure OSPF protocol on interface em0:

[edit]
root@juniper2# set protocols ospf area 100 interface em0.0

2.5 Next, Juniper 2 must take the routes it receives from RIP and redistribute them into OSPF, for this purpose create the following policy:


[edit]
root@juniper2# set policy-options policy-statement rip-ospf term 2 from protocol rip
root@juniper2# set policy-options policy-statement rip-ospf then accept

2.6 Apply the policy to OSPF:

[edit]
root@juniper2# set protocols ospf export rip-ospf

2.7 Now, create the policy for routes redistribution from OSPF into RIP :

[edit]
root@juniper2# set policy-options policy-statement send-default term 1 from protocol ospf
root@juniper2# set policy-options policy-statement send-default then accept

2.8) Apply the policy to RIP :

root@juniper2# set protocols rip group small-rip export send-default

3 Configuration on Juniper 3:

3.1. Configure OSPF protocol on interface em0:

root@juniper3# set interface em0.0 family inet address 192.168.1.5/24
root@juniper3# set interface em1.0 family inet address 10.1.1.1/24
root@juniper3# set protocols ospf area 100 interface em0.0

Now, routes from Juniper 1 are advertised to both routers Juniper 2 and Juniper 3. You can test it with ping command. Good Luck.
