Cisco 837 ADSL Set up !
HI there,
I've done a basic config on a Cisco 837 for ADSL connection .... Config is below (with dummy ip's and passwd) that if it will work when i give it the real passwords, ip, etc ? One thing I dont understand is that router shows 4 interfaces ... ethernet 1 - ethernet 4 and 1 ADSL interface ofcourse .... When I do a show ip int brief on the router, it shows me 4 fastethernet interfaces (L2) and two ethernet interfaces (L3) ... I have assigned my I.P to ethernet0 which i cant physically find on the router ? can someone tell me how its like with 837 series router....given below are my show run and sh ip int brief ?
Main Question:
1. Is config for ADSL connection ok ?
2. Where is interface ethernet 0 ?

hi there,
i just realized tht my backup adsl line on which i can test connections is not available for atleast another 1 week ... So I will post my results in about 1 week time ...

your configuration worked ... just tested it today by bringing the 837 home and tested it with adsl line ..... thanks for that...
now the question is that on my cisco 837 router, i have 4 interfaces and 1 adsl interface ... the interfaces are named ethernet 1,ethernet 2,ethernet 3,ethernet 4.....but when i do sh ip int brief,
i see ethernet 0, ethernet 2, fa 1,fa2,fa3,fa4 ...
only when i plug my ethernet cable from PC to ethernet 1 or ethernet 2, and then check interface status, it shows ethernet0 as up ...
I'm just kind of confused how it works with cisco 837 where it shows me interfaces ethernet 1-4 whereas in config, it shows me interfaces ethernet0, ethernet2, and 4 fast ethernet interfaces ? ?

sorry if i made the above confusing ... All I'm after is that physically when i look at the router I see the following interfaces
ethernet 1, ethernet2, ethernet3, ethernet 4
but when i do sh ip int brief or show run (as i did above)
i see ethernet 0, ethernet 2, fastethernet 1,2,3 and 4......
why the mismatch and which 1 is which ? or am i making a silly mistake here ?

no this is noraml
your active interface is ethernet0
and your switch L2 interfaces are
FE0,1,2,3
and forget others

yes, but how do u explain that ethernet0 interfaces (the layer 3 interface) , where does it exist on the router ? is it a logical interface by default in 837 ?

I shall copy paste this config at work tomorrow and reply you with the results .... regarding ethernet0, it does appear in teh config but i just cudnt figure out the exact physical interface for it ... I'll double check it again at work tomorrow though !
