We have two Juniper SRX340's. We have two reth's configured on them (one for the outside one for the inside). Each side connects to a pair of stacked cisco switches on which we have etherchannels configured.
Each reth on the Juniper has 4 ports (2 from each Juniper). We have the Juniper's configured in Active/Standby mode therefore at any one time there are two ports active on the reth.
The issue we have is that we appear to have a primary port on the reth configuration. For example the one reth has port 6 and 7 configured. If I remove the cable from port 7 we see no issues on the network. If I remove the cable from port 6 we instantly lose OSPF neighbors. I have also tested adding another port to the reth so a single device has three ports but we still see the same issue with disconnecting port 6.
We have this problem on both reth's...
