I am trying to configure a GRE tunnel between a CE6850 & a Cisco Catalyst 6509 switch.
However the tunnel will not come up on the 6850, although i have layer 3 connectivity between the source & destination ip address's. Can anyone help?

CE6850 configuration...
interface Tunnel0
 ip address 192.168.121.1 255.255.255.252
 tunnel-protocol gre
 source 10.163.50.14
 destination 10.34.75.2

Cisco 6509 configuration...
