[c-nsp] transparent bridging question

[Frank Cisco]

Hi

We have customer using Serial interface but on our site we only have
Ethernet interface and will run bgp. Customer doesn't have any spare
ethernet port and we also doesn't have spare serial interface. So we plan to
put one small cisco box (1601 series) in the middle as the cost is cheaper
than serial-to-ethernet converter.

Customer'sRouter------(serial-intf)------Cisco-1601------(Ethernet-intf)-----Our
Router


In cisco 1601 will configure :

interface ethernet 0
 bridge-group 1

interface serial 1
 bridge-group 1

bridge 1 protocol ieee


Will this topology will work ? Anybody has experience with it ?
