Old thread, but we are having a very similar issue. When a customer HA Palo Alto router fails over, it is killing the OSPF process on our side.yes L1 is good. also some of the bgp peers that drop are on a separate port and dedicated fiber outside of the ospf L1
the problem happen when a paloalto or fortigate firewall with ospf to the ccr's fail over between the active and the passive firewall device.
but fortigate ospf (and unrelated global bgp on different L1) should not drop when paloalto do a failover, or vice versa.
it simply seems like the whole routing engine on ccr dies and restarts.
it is good that ospf and bgp do not die together in ROS7.
Any resolution besides ros7?
We have not yet tested ros7 in this network due to the complexities of OSPF, MPLS, VPLS, and L3VPN.
