Greetings,
Can someone clarify for me the following
I have a MVPN topology that i am maintaining. There is a new feed that i have to set up using I-PMSI. Not a problem I can just grab the configuration from a working deployment to adjust. As part of the design, there is a virtual-router instance configured for OSPF. The adjacency would not come up unless I added a loopback and made the interface part of the instance.
1. On JunOS , is it required to have a loopback address to bring up an OSPF adjacency? It seems like it but i never had this issue before when setting up a peering between devices not using a virtual router instance. I believe the rules for selecting a routerID are highest loopback address OR highest physical IP address.
2. Is a loopback needed for MVPN configuration? Our current deployment has it but in my testing on my lab multicast works without a loopback configured.
