Same Sub-Net w/two 1751 Routers

New install - Two 1751 routers each with a WIC-1T serial card in slot 0. I have router A set as 192.168.0.21 with port unnumbered. I want router B to be on the same subnet - 192.168.0.22 w/port unnumbered also. It gives me a conflict when I attempt to have both on the same subnet. I have done this in the past with the same model router and a DSU card. But for the life of me I can't remember how. I hope some of you more experienced router folks can help me out. Thanks in advance. LDB

hi

You probably did configure bridging.

Here i have you a link to how you can configure brindging.

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fibm_c/bcfpart1/bcftb.htm#1002360

==> search in the page for: "Ethernet Bridging Configuration"

I guess that what you looking for.

Still i would recommend you to do a readdressing at one location, so you can

route between the two sites.

Hopes that helps you

Re: Same Sub-Net w/two 1751 Routers

What you can probably do is create a loopback interface with the ip address with mask 32.

like in router A, give ip address 192.168.0.21 255.255.255.255 and use this for unnumbering

in router B, give ip address 192.168.0.22 255.255.255.255 and use this for unnumbering
