Juniper OSPF Neighboring with Avaya ERS 5632
« on: May 25, 2016, 09:10:30 PM »
I have an issue with trying to get an SRX 220 interface to neighbor with an interface on an Avaya ERS5632.

The interfaces are setup to use a /30 IP address. Avaya 172.31.100.221/30 and SRX 172.31.100.222/30. Nothing is seen on the Avaya side with regards to any neighboring.

From the Juniper side, I can see that the IP from the Avaya side is trying to Hello and the state is stuck in init.

The SRX logs also show that the IP from the Avaya was absorbed.

I tested the configuration using 2 SRX devices, and no issues. I have other devices, both Avaya and Cisco able to neighbor without issue.

Any ideas on what might causing the interop issues? OSPF values on the Avaya are using the default and the type is broadcast. SRX also using default values.

Is the Avaya/Juniper showing that it is dropping large frames maybe?  Seen it a few times where there can be an MTU issue between vendors if they use VLAN's and OSPF as they need a larger MTU to accept the packets.

I've had that issue when tagging is incorrect or the vlan ingress filters don't match on the Avaya side.
