Hi,
How to create a bridge mode in router and switch?

For using bridge mode u have to enable integrated routing and bridge mode with 'bridge irb command'.Then u create a brigde virtual interface(BVI) which behaves like representing entire bridge group pointing to routed interfaces in the router.
BVI needs to be assigned a BVI group no.This no.acts as the relation pointer between the BVI interface & the bridge group.
like below:
int fa0/1
no ip address
duplex auto
bridge-group 64
int bvi64
ip address 192.168.2.2 255.255.255.0
ip access-group 130 in
ip nat outside
ip nat inside source list 5 inteface BVI64 overload
ip route 0.0.0.0 0.0.0.0 192.168.2.1
bridge 64 protocol ieee
bridge 64 route ip
the sample above shows BVI being enabled with grpno. 64.this is further referenced to the actual physical interfaces as they arent involved in actual routing.
the bridge group is referenced with the protocol it will support...in this case IP.
Pls rate/mark if this helps!!!

Hi,
We are using Leased line link with ISP between two Cisco router A and B.The A router connected to Head Office and similarly B router connected to Branch Office.The concept is we have to configure the bridge between the two routers.This will be point to point connection.
What would be the configuration for both the routers?

Hi,
do not use bridge for this application. Use nornal IP addressing with different subnet for each sites.
Using bridging expose you to broadcast traffic crossing the link, difficulty in diagnosis, impossiblity of doing poer QoS, end other problems. Generally speaking, bridging is a poor practice and should be avoided whenever possible.
