I have a pair of VM 300s in active/active mode and everything is running OSPF. PA1 is primary and PA2 is standby. I noticed I was missing a bunch of traffic for anything going to the standby router. I can ping every interface on the standby sourced from the loopbacks on each router but I cannot route through the standby.
The OSPF table shows both PAs as available paths but anything going through the standby doesn't work. If I add static routes on the standby PA and both routers to force traffic through the standby it is broken 100 percent of the time. If I force traffic through the primary everything works. The same holds true if I flip the primary/standby where PA1 is standby and PA2 is primary the problem flips and again the standby cannot route traffic even though I can ping every interface on both PAs to include tunnels and loopbacks.
