bridge-group on serial interface on ISR4000/IOS XE?

[jirka.novak]

Hi,

with ISR29xx we were used to using such configuration:

interface serial 0/0/0:0

  encapsulation ppp

  bridge-group 10 

  ppp bridge ip

!

interface bvi 10

  ip address 10.0.0.2 255.255.255.0

With ISR4000 we found that it is not possible to use bridge-group command any more.

I found that for ethernet interfaces it is possible to use EVC feature with 'interface BDI' command. But it works with ethernet interfaces only.

Is there any new syntax how to use old bridge-group on IOS-XE?

Thank you for any advice.

Hello,

in meantime I found solution for our case...

What I missed in my original description is that other side of PPP connection is modem/bridge with PPP (patton modem in our case). This modem is capable PPP half-bridge feature.

To interface with such modem we use configuration above on ISR 29xx. In other words, there is the only one interface in bridge group (int serial 0/0/0:0) and it allows ISR to cooperate with PPP half-bridge device.

We found that on ISR4xxx, you don't have to use bridge group to make it running:

interface Serial0/1/0:0
ip address 10.2.0.1 255.255.255.248
encapsulation ppp
ppp bridge ip

Sincerely yours,
