1604 Internet Router Config

[Speaker]

I know I'm missing something really easy here.

I have a backup T1 to the Internet and a 1604 for connectivity.

I ended up basically copying the config of the working internet router (also a 1604) and changing the IP addresses, but still no luck.

I'll paste the configs of both routers:

!
version 11.2
service timestamps debug uptime
service timestamps log uptime
service password-encryption
no service udp-small-servers
no service tcp-small-servers
!
hostname Routerthatdoesntwork
!
enable secret 5
enable password 7
!
ip subnet-zero
no ip domain-lookup
!
interface Ethernet0
ip address 38.A.B.C 255.255.255.248
no ip directed-broadcast
no keepalive
!
interface Serial0
ip address 38.A.Y.Z 255.255.255.252
no ip directed-broadcast
[note: the first two octets are the same as e0, but they are different groups of addresses]
!
router rip
version 2
network 38.0.0.0
no auto-summary
!
ip classless
ip route 0.0.0.0 0.0.0.0 Serial0





This is the router's config that works.



version 11.2
service timestamps debug uptime
service timestamps log uptime
service password-encryption
no service udp-small-servers
no service tcp-small-servers
!
hostname Routerthatworks
!
enable secret 5
enable password 7
!
ip subnet-zero
no ip domain-lookup
!
interface Ethernet0
ip address 64.211.A.B 255.255.255.240
!
interface Serial0 [not used]
no ip address
!
interface Serial1
ip address 64.208.C.D 255.255.255.252
service-module t1 remote-alarm-enable
!
router rip
version 2
passive-interface Serial1
network 64.0.0.0
no auto-summary
!
ip classless
ip route 0.0.0.0 0.0.0.0 Serial1




The only difference is that the [backup] router has an external CSU/DSU (which is working and can be seen by the ISP) while the existing Internet router has a WIC. The backup was previously used at a branch office in a frame-relay network. I changed the encapsulation from ansi to hdlc, though that doesnt show in the config. I eventually need to implement a failover and load-balancing between the two routers, but I can't even get it to connect by itself right now.

I have no connectivity to the Internet through the new router. I cannot telnet to the new router. When consoled in, I can ping the ethernet interface, but not the serial interface of the new router.

TIA

do a "sh ip int s0" so we can see the status of the interface..
might give an idea..

Also do a sh controllers s 0

I wish I could (and I wish I had saved the outputs when I did) because I'm curious as to what the problem was.

This weekend I swapped out the non-working router with a new 1721, which was on the agenda anyway. It worked like a charm. I think there was something in the initial (1604)router setup (configured for a frame-relay circuit) that I forgot to change.

Thanks for help!
