Hi all,

I am wanting to configure a bridge over a WAN link between two cisco routers. The media is a leased line and the resultant network will be a private network. The setup is as follows:

R1

bridge irb
 
interface FastEthernet0/0
 no ip address
 full-duplex
 bridge-group 1
 
interface Serial0/0
 bandwidth 2048
 ip address 179.16.0.126 255.255.255.252
 encapsulation ppp
 no fair-queue
!
interface FastEthernet0/1
 ip address 252.50.50.6 255.255.255.0
 duplex auto
 speed auto
 !
interface Serial0/1

 bandwidth 2048
 no ip address
