can't ping across l2tp tunnel after switching HP procurve for 3750x switch
Here in our remote office we get dhcp from our corporate office via a L2TP tunnel between two 2901 routers. This was working fine, until I replaced our old hp procurve 1800 switch with a new 3750x switch, and now I can't get the layer 3 working across the tunnel.
quick diagram: remote hosts----> 3750x --->2901 l2tp <--------->2901 l2tp -----> HP procurve ------> corporate office/servers/dhcp server
my first thought was it was just not letting dhcp through, but then I assigned a static ip address on my remote end, and I still can't ping across to the corporate office.
The l2tp tunnel is up, because I can see the MAC address on the corporate site if I do a: show mac address-table.

Total Mac Addresses for this criterion: 66
Gi 1/0/17 is the port on the 3750x switch that is connected to the 2901 router, and it shows about 30 MAC's learned from the corporate office on VLAN 1.
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
