I have 2 3750s supporting a building. They have a direct link betwixt them with a vlan range trunk allowed over this link. Some of the vlan interfaces are not seeing each other and I have no idea why. This is a common config on our environment but this setup is giving me problems. one router can see the a test device in arp the other cannot. The standby shows some HSRP vlan pairs a couple report 'unknown' and each reporting themselves as Active:LOCAL. Shutting down one side does not force traffic flow.
This what I get from a switch with a link to each router. .49 being the HSRP ghost addr.
I'm not understanding how one vlan interface works fine while others do not even through they are in the same trunk vlan range and config'd the same. Ideas?
