I am trying to implement Cisco GLBP on 2 Cisco 2821 routers with the following setup (see diagram below).
As when I link up the 2 Cisco2821 without going thru the switch I am able to ping to both Cisco2821 and also to the virtual ip.
Cisco2821(1)-- Core Router1 --Cisco2821(2)
While both Cisco2921 connects to a single Cisco3750
Can anyone one advise if such setup is possible and if possible what are the configuration I need to look into on the switch (on the 2 ports connected to the 2 Cisco2821)?
What is the topology when it works and what is the topology when it doesn't work?

All connections need to be on the same vlan. Are you sure the connections on your layer 2 switch are on the same vlan as the routers? Are you absolutely sure the ports where your routers are connected are really layer 2 (I saw that your switch was a 3750 which is a layer 3. You need a command to make it layer 2)
