We are having some strange arp issues in one vlan. Suddenly, some devices (not all of them) from vlan 1 are not able to ping vlan 2. Interface vlans are located on different switches and I have to manually clear arp in vlan 1 to make computers ping each other between vlans.
We have set arp timeout command in vlan 1 but it does not help until I manually clear it
We have mst in place, but vlan 1 in our case is located on a root bridge and switch with vlan 2 is directly connected to it. I also suspected STP but this is happening with a root bridge and only for these 2 vlans with some computers. All other vlans are accessible
Affected computers (for now these are just 2 mail servers located in vlan 1) are not able to ping any vlan on switch 2. Nothing is blocked by STP.
Mail server 1 is connected to Root bridge vlan 1, mail server is connected to another switch in vlan 1. Both servers are configured as a Cluster with Microsoft Exchange 2010. I suspect this could be a cluster issue, but not sure
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
