Hi, this seems very basic, however, I am needing some clarity on why I cannot peer OSPF between either in the following scenarios:
1. a pair of SRX4100s (one is a Chassis Cluster with reth and one is stand-alone with irb)
According to the diagram, layer 3 in scenario 1 is across a circuit (reth0.700 <--> irb.700)
2. above SRX Cluster and Cisco 6800 switch.
According to the diagram, layer 3 in scenario 2 is between reth0.800 and Vlan800, directly.
All devices show traceoptions/debug sending ospf.
All have matching mtu, and can ping the directly connected interfaces of the other host.
At Layer 2, the link between the SRX firewalls go via the C6800 switch.
