We have a very odd problem that we've been dealing with for a couple of weeks. JTAC is involved but we have not come to a resolution yet. The gist of the problem is that we have two MX960s and we're running VRRP on multiple interfaces with different Cisco switches in between each pair of Juniper interfaces.
[J] ----- [C]----[C]------ [J] The switches are just layer two and we're running VRRP on the routers. The problem is that one day, three of the interfaces on the backup router suddenly stopped receiving VRRP messages from its peer. JTAC seems to think that the Cisco switches just suddenly stopped forwarding VRRP messages to the backup router, but that makes zero sense unless some bizarre issue just happened to occur on multiple unrelated switches at exactly the same moment. I'm still leaning toward a problem on the router. Which leads me to my question. What is the risk of restarting the VRRP process? I see we have "soft" and "graceful" as options. Both sound fairly low-risk. I'm tempted to just restart the process on the backup router to see if that fixes the problem. What do you think?
