I'm reposting this because I inadvertantly marked my question as solved, but it isn't. I still can't get inter-vlan routing going on my 3750 ip-base switch. The 3750 has two VLANs, each linking to its own 2950. I just want vlan 1 hosts on one 2950 to route to vlan 2 hosts on the other 2950. It's driving me crazy...
Okay, here's my config on the 3750. As you can see, my vlan SVIs are up and running and I can ping a host on vlan 1. however, when i try to use extended ping to reach that same vlan 1 host from vlan 2's SVI, it times out. my vlans do indeed have the vlan 1 SVI as their default gateways.
Please help!!
Matt
