Hi,
I have a requirement to bridge 3 ATM Subints, and one dot1Q int - Would the following allow layer2 connectivity between the 4 Ints?(So client could run single subnet across all 4 sites):
bridge irb
interface ATM1/0.37 point-to-point
description ATMI ClientA_1
bandwidth 512
no ip route-cache
bridge-group 11
pvc ClientA_1 11/37
tx-ring-limit 3
oam-pvc manage
encapsulation aal5snap
!
!
interface ATM1/0.38 point-to-point
description ATMI ClientA_2
bandwidth 2000
no ip route-cache
bridge-group 11
pvc ClientA_2 11/38
tx-ring-limit 3
oam-pvc manage
encapsulation aal5snap
!
!
interface ATM1/0.39 point-to-point
description ATMI ClientA_3
bandwidth 1000
no ip route-cache
bridge-group 11
pvc ClientA_3 11/39
tx-ring-limit 3
oam-pvc manage
encapsulation aal5snap
!
interface FastEthernet0/0.40
description ClientA_4
encapsulation dot1Q 40
bridge-group 11
bridge 11 protocol ieee

Also add bridge 1 route ip. I think it may have been added by default. sh bridge group 11 will show if the interfaces are forwarding.

#show run | include bridge
bridge irb
bridge-group 11
bridge-group 11
bridge-group 11
bridge 11 protocol ieee
bridge 11 route ip
It was there...I only have the three atm subints added to bridge 11, but I don't believe the client-ends have the routers connected as yet:
If I remove, then add "bridge 11 route ip", I get the following:
#show bridge group
Bridge Group 11 is running the IEEE compatible Spanning Tree protocol
Port 21 (ATM1/0.37 RFC 1483) of bridge group 11 is listening
Port 20 (ATM1/0.38 RFC 1483) of bridge group 11 is listening
Port 22 (ATM1/0.39 RFC 1483) of bridge group 11 is blocking
Then after ~10 seconds:
#show bridge group
Bridge Group 11 is running the IEEE compatible Spanning Tree protocol
Port 21 (ATM1/0.37 RFC 1483) of bridge group 11 is blocking
Port 20 (ATM1/0.38 RFC 1483) of bridge group 11 is blocking
Port 22 (ATM1/0.39 RFC 1483) of bridge group 11 is blocking
Is that normal?
