I have a weird problem I can't figure out, hoping one of you folks can assist.
I have around 100 HP switches (mostly 8350's - as is the case in this story) across the country and an IMC server in the datacenter.
At a handful of our locations we have failover routes, if the MPLS goes down the router directs traffic to a VPN appliance at .2 and the important traffic is let through until the MPLS is restored.
When a location fails over, the switch learns that its new route to our IMC server is through the VPN appliance at .2 and it won't forget that, so when the MPLS comes back online the IMC server can't communicate with any of the switches at the location that recently failed over because it's using the MPLS path to communicate and they're trying to reply over the VPN tunnel.
When trying to communicate to anything else on the same subnet as the IMC server the switch uses it's default gateway as configured.
Is there anything I can do aside from rebooting the switch to make it use the default route and stop thinking it knows better than its configuration?
