    I have this topology.

    I got the following for ospf
    {master:0}[edit]
root@sw1# run show vrrp

                                                                mas    128.208.0.151

    from the traceoption, I have the following
    Apr  7 02:35:24.219111 OSPF restart signaling: Received hello with LLS data from nbr ip=128.208.0.149 id=10.220.1.3.

    128.208.0.149 is irb ip on R1 and 10.220.1.3 is R1 loopback IP.

    I searched the internet to find this following

    OSPF and VRRP issue
    hi everyone, i am having an issue after configured OSPF within our infrastructure. i get an INIT state between on 4506 Cisco L3 switch and one Nokia IP330 firewall. I believe is something to do with VRRP configured between the IP330s but i cannot figure out where the problem is.

    Anyone knows anything similar on Juniper ?

    thanks !!

    I did some search in the internet. seems running routing protocols on VRRP is really not recommanded. I guess BGP might have  similar issue too, not test yet.

    Instead of running the routing protocol on the virtual ip run it instead on both of the physical interface ip addresses.

    Seems really not recommended way to run routing protocols on VRRP.
