Basically you looped two FE ports together. Pick 1 port for your layer 3 routing and the other port to cross connect your layer two tunnels. The vlan ID for the two FE ports must match. The tunnels reference the loopback of the endpoint router. Hope this helps. -Doan Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=75266&t=75255 -------------------------------------------------- **Please support GroupStudy by purchasing from the GroupStudy Store: http://shop.groupstudy.com FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html
