VXLAN NVE peers not up

Hi All,

Thanks in advance for looking at my issue.  I've seen lots of people report this but I'm not able to resolve it at the moment so would appreciate some assistance.  I've setup VXLAN and I can't get L2 routes advertised across NVE peers.  The BGP neighbours are peered and each end shows the routes are being advertised but the other end doesn't show them.  The underlay network is all good and I can ping between the Loopback interfaces used for BGP and NVE peering.  I can also ping into and out of the VXLAN environment as long as the return patch is through the same local network.  I've attached a text document detailing the four switches in the design along with some show commands.  Switch 1 and 2 are layer 2 adjacent, 3 and 4 are also adjacent and there's a layer 3 network between them.

 

thanks again for taking the time to look.
