Hi,
For some reason my original response to this didn't
make it...
To do router -- switch -- router , each router-switch
connection would be it's own etherchannel. The switch
needs to be configured for channeling on the 2 ports
connecting to router1 and also on ports going to
router2. On the switch, this would be 2 channel groups
w/different admin group #s. I would also set the
channel to on as well.
On the routers you would have a config like:
int fastethernet0
no ip address
no sh
channel-group 1
int fastethernet1
no ip address
no sh
channel-group 1
int port-channel 1
ip address x.x.x.x y.y.y.y
etc...
no sh
If you're doing VLAN trunking over channel, then you
can configure VLAN encapsulated sub's on the
port-channel like:
int port-channel 1
no sh
int port-channel 1.1
desc vlan 1
encaps dot1q 1
ip address 1.x.x.x y.y.y.y
int port-channel 1.2
desc VLAN 2 -- NATIVE VLAN
encaps dot1q 2 native
ip address 2.x.x.x y.y.y.y
