I have a 2611 with an upstream frame T1 on s0/0 and a normal (subnetted) LAN on e0/0.
I was recently asked to provision a DSLAM (Coper Mountain CE150) such that all remote systems appear to be on the local LAN. Hey now, don't tell ME it's stupid, I know it is.
My other network with an identical DSLAM routes /30s to the DSLAM which works beautifully.
The CE150 can work with an IRB in order to do something it calls Virtual WAN -- wherein all remote ends appear to be on the local LAN. Sounds like exactly what I want to do.
I follow the example given and try to modify it as I go, since it is assuming that the IRB group is set up over frame relay:
!
in e0/0
ip address 192.168.1.0 255.255.255.224
!
in BVI1
mac-address 0000.0c00.338c
ip address 192.168.1.253 255.255.255.252
no keepalive
!
bridge irb
bridge 1 protocol ieee
bridge 1 route ipp
!
On the CE150 I have the ethernet port set up as VWAN networking model with its IP as 192.168.1.254/30.
When I add "bridge-group 1" to the e0/0 configuration all my normal e0/0 traffic stops, then a number of packets to hosts on the /27 network on e0/0 work, but then the entire thing seems to fall down. At no point am I able to ping 192.168.1.254. I added an ip route to that particular /30 through device bvi1 just to see if that'd help but no dice.
Is what I'm trying to do possible? Or does IRB require a dedicated interface?
