857 as modem

Unanswered Question
Jun 21st, 2008


I have one 1811 and one 857 router to get the adsl service. So I need to configure 857 in bridge mode and 1811 as pppoe client, so the wan ip address is assigned to the 1811 fastethernet interface.

My question is can I set up a private ip address for 857 so I can change or monitor via lan port?

Can I enable irb and assign ip to BVI1?

In this way, as atm0 interface is bridged to vlan1, will it interfere with the pppoe connection?

Any thought is appreciated?

I have this problem too.

Yes, you can do that. But if you get a 1801 instead of the two routers, that would be better.

Hope this helps, please rate post if it does!
