Good day;

I have a pair of layer 3 switches one is an Arista switch and the other is a Cisco switch.  They are connected together over a PTP 10 gig circuit. What is going on is that about 2-3 times a day I get am getting am OSPF Adjacency teardown/establishment dude to DD patch mismatch.  Now I have checked the MTU size on both ends and they are set to 1500 bytes, carries says that the circuit is clean.  The only other difference I see on the config is that the Arista switch the max/min hold times for SPFs are 5000msec while on Cisco it is set to 10000msec.  Is there anything else I am missing?  What else can I check?

Thank you in advance!!!

Warren

Hi Warren, 

I would recommend opening a TAC case to look into this issue since this will require more logs and possibly packet captures to debug ospf adjacency. You can either send an email to support@arista.com or call support hotline.
