Hello,

I'm having a problem with the configuration of a Cisco 878.
What i'm trying to do is configure 2 PVC's.

One is a PPPoA connection, and the other a RFC 1483 connection, in
full bridge.
The thing that i can't get to work is using the 2 connections
similtaniously.

I'm using the following config:

----------------------------------------------------

There are 2 VLAN's. VLAN 1 i'm using for the RFC 1483 connection, and
VLAN 250 for the PPPoA connection.
With this config, the PPPoA connection works. When i go into global
configuration mode, and enter the command 'no ip routing', the RFC
1483 connection works.
The gateway of last resort disappears, and the routing table is shut
down.
After this, when i enter 'ip routing' in Global config mode, and 'ip
route 0.0.0.0 0.0.0.0 Dialer0', the PPPoA connection works.

Does anyone have a solution that fixes my problem?

Thanks in advance.

If I recall correctly - and it has been a while - the
router will NOT bridge IP packets when
routing is enabled???

Unless you configure CRB/IRB?

Here is a successful config with rfc1483
that has an IP address on the router.
This mayy not be what you want but maybe
will point in some useful direction.

ip cef

bridge irb ! ###
!
interface FastEthernet0/0

ip route 0.0.0.0 0.0.0.0 6.23.17.1
!

bridge 1 route ip ! ###
!

Thank you. I have a working config with RFC 1483, so that's not the
problem.
It's true that the cisco will not bridge IP packets with routing
enabled. When i disable it, it works fine. The problem is the
combination of both.

Thanks.
