Is it possible to bridge a C1117-4P and a Aerohive Router?

[MarcelSmal]

Hi Everyone,

Is there anyone that can help me I am struggling to see if you can bridge a Cisco C1117-4P router. As I cant seem to get the device to talk to another Aerohive XR600P router. We are trying to test a solution that I want to use with some point to point connections.

I have attached the config of the router. Can you guys please help me as I used the guides from the cisco site but not getting it working?

@MarcelSmal : 

IOS-XE doesn't support the legacy bridge groups, it uses BDI. Check the document below. IP Base should in theory be sufficient. Can you create service instances ?

not sure we understand your question, you want to make 2 bridge devices to pass the traffic  ?

we miss the config you mentioned here?

@inderdeeps I see thought that it will be possible as I read somthing like the article that you posted.

@balaji.bandi I want the cisco router to act as the bridge and pass the adsl connection traffic to the other router.

I see the config was not attached.

Hello @MarcelSmal ,

your WAN interface is the following:

interface ATM0/2/0.1 point-to-point
description connection to service provider
atm route-bridged ip
no atm enable-ilmi-trap
pvc 0/34
vc-hold-queue 1024
encapsulation aal5snap

if this sub intereface does not accept the command bridge domain 100 you cannot bridge.

Try and report the results.

Hope to help

Giuseppe

Thanks for letting me know.

@Giuseppe Larosa when I try to issue that command it gives me a % unrecognized command. So it seems that you cant bridge it like I need it to.

[Giuseppe Larosa · Accepted solution]

Hello @MarcelSmal ,

look for a routed alternative as bridging is not available between the ATM interface and the LAN interface on the Cisco router.

You can even use NAT on the Cisco router as a way to help the downstream device to reach the internet.

Hope to help

Giuseppe

Sorry to resurrect this thread. I'm trying a similar thing with the same C1117-4P. The difference is I don't use PPPoE, so no Dialer interface.

Wouldn't it be possible to bridge Ethernet0/2/0 with GigabitEthernet0/1/0, or does that still count as the "ATM" interface. When I looked at https://www.cisco.com/c/en/us/td/docs/routers/asr1000/configuration/guide/chassis/bdi.html it said the only limitation there was "PPP over Ethernet (PPPoE)".
