I'm trying to connect two switches with a g.shdsl connection:
switch--Cisco828---<line>---Cisco828--switch
This setup should replace an unstable LRE link.
The 828 routers are each connected to a switch with the ports set in trunking mode. The config below works
fine for VLAN1 traffic, however all other VLANs are not bridged.
bridge irb
!
interface Ethernet0
no ip address
bridge-group 1
!
interface ATM0
no ip address
no atm ilmi-keepalive
dsl equipment-type CO ! set to CPE on the other side
dsl operating-mode GSHDSL symmetric annex B
dsl linerate AUTO
!
interface ATM0.1 point-to-point
bridge-group 1
pvc 0/35
encapsulation aal5snap
!
interface BVI1
ip address 172.25.8.14 255.255.255.0
!
bridge 1 protocol ieee
bridge 1 route ip
So my initial idea was to use dot1Q trunking and create subinterfaces with additional bridge groups for the VLANs required:
interface Ethernet 0.1
encapsulation dot1Q 1
bridge-group 1
!
interface Ethernet 0.2
encapsulation dot1Q 2
bridge-group 2
!
interface ATM0.1 point-to-point
bridge-group 1
pvc 0/35
encapsulation aal5snap
!
interface ATM0.2 point-to-point
bridge-group 2
pvc 0/36
encapsulation aal5snap
!
!
bridge 1 protocol ieee
bridge 1 route ip
bridge 2 protocol ieee
But....the 828 does not support dot1Q encapsulation on the ethernet port. Anyone has an idea on how to solve this? A layer 2 connection is required for the security gateway (security is based on mac addresses).
