We normally interconnect an ethernet VLAN via a bridge-group to an ATM PVC like :
interface ATM1/0.162055
bridge 10
pvc 16/2055
encap aal5snap
!
interface port-channel1.10
encapsulation dot1q 10
bridge 10
!
bridge 10 protocol ieee
This works fine on our 7206VXR's (IOS 12.4(24)) but the limit on bridge-groups is 256 which is not scalable enough.
Earlier i was reading on http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/fslocal.html#wp1170945 for L2 switching an ATM PVC to an Ethernet VLAN which interested me because of the simplicity of it. According to the manual, the corresponding config would be :
interface ATM1/0
pvc 16/2055 l2transport
encapsulation aal5snap
!
!
connect atm-eth-vlan-con atm1/0 16/2055 GigabitEthernet0/1.100 interworking ethernet
I've got the following questions :
- Can i terminate the ATM PVC to a port-channel or is it implicit when i configure gi0/1.100?
- Are there any limitations on the amount of connects on the 7200VXR with the IOS i'm using?
- Are there any other caveats i didn't think about?
Thanks a lot!
