• Example
host1:pe1(config-router-rn)#ttl 35
• Use the no version to restore the default value, 1 second.
• See ttl.
update-source
• Use to specify the loopback interface whose local IP address is used as the source
address for the OSPF connection to a remote neighbor.
• Example
host1:pe1(config-router-rn)#update-source loopback 1
• Use the no version to delete the source address from the connection to the remote
neighbor.
• See update-source.
Configuration Tasks
At a minimum, perform the following tasks on each PE router to configure them for OSPF.
For other OSPF configuration tasks, see OSPF Configuration Tasks in the JunosE IP, IPv6,
and IGP Configuration Guide.
1. Create the VRF.
host1(config)#ip vrf ospf2
Proceed with new VRF creation? [confirm]
host1(config-vrf)#rd 100:85
host1(config-vrf)#exit
2. Start OSPF on the VRF, either from the parent VR or directly from the VRF.
From the parent VR:
host1(config)#router ospf 5 vrf ospf2
From the VRF:
host1(config)#virtual-router :ospf2
host1:default:ospf2(config)#router ospf 5
The command prompts in the remaining steps reflect using the latter method for
starting OSPF.
3. Configure the OSPF domain ID.
host1:default:ospf2(config-router)#domain-id 45
4. Configure the VPN route tag.
host1:default:ospf2(config-router)#domain-tag 1200
5. Redistribute routes learned from other PE routers back into OSPF.
host1:default:ospf2(config-router)#redistribute bgp
6. Create an address family in BGP.
