Bridge btw pvc and vlan 1

[nmdc.kzstan]

Hi,

Here is the current Cisco 877 configuration:

bridge irb

!

!

interface ATM0

no ip address

no ip mroute-cache

no atm ilmi-keepalive

dsl operating-mode auto

!

interface ATM0.1 point-to-point

no snmp trap link-status

pvc 0/40

  encapsulation aal5snap

!

bridge-group 1

!

interface ATM0.2 point-to-point

no snmp trap link-status

pvc 0/41

  encapsulation aal5snap

!

bridge-group 2

interface FastEthernet0

!

interface FastEthernet1

!

interface FastEthernet2

!

interface FastEthernet3

switchport access vlan 2

!

interface Vlan1

description $ETH-SW-LAUNCH$$INTF-INFO-HWIC 4ESW$

ip address 192.168.2.254 255.255.255.0

ip nat inside

ip virtual-reassembly

ip tcp adjust-mss 1452

!

interface Vlan2

ip address dhcp

bridge-group 2

Bridging between pvc 0/41 and fa 3 is needed so that ip phone connected to fa3 is assigned ip address by ISP's DHCP server. If BVI2 interface is created it gets dynamic ip, ip phone does not. What did I miss?

You missed

bridge 1 protocol vlan-bridge      &

bridge 1 route ip

Hi Rama,

I had following lines configured that I forgot to copy:

bridge 1 protocol ieee

bridge 1 route ip

bridge 2 protocol ieee

bridge 2 route ip

Tried "vlan-bridge" instead of "ieee" with no luck.

Oops, I was looking at something else.  The one I gave was for bridging a vlan and an ethernet port.

There is a way to bridge a FR PVC and Ethernet with the following command.

frame-relay map bridge  broadcast

I will check if there is ATM substitute

Did you use

atm route-bridged ip

on the ATM sub-interface?

[nmdc.kzstan]

Yes, I tried it too.

Here the same problem was resolved by configuring CRB instead of IRB.
