Okey dokey :)
3 routers:
eo1 Cisco 2516 2 Serials s0 and s1, 1 ethernet (hub).
e0: 172.16.1.40/16
s0: 10.10.10.10/24 (creative huh?) s0.1
s1: 10.10.30.1/24 s1.1
eo2 Cisco 1602r 2 Serials (56K 4 wire dsu), 1 ethernet
e0: 192.168.1.1/24
s0: 10.10.30.2/24 s0.1
s1: 10.10.20.2/24 s1.1
eo3 Cisco 2610 2 Serials (1 56K 4 wire dsu) , 1 WIC-T1, 1 ethernet
e0: 192.168.200.1/24
s0: 10.10.10.11/24 s0/0.1
s1: 10.10.20.1/24 s0/1.1
just a basic run down.

There ya have it. Ip connectivity is verified on all hosts to their neighbors.
Dynamic routing is pooh though. I was running ospf happily until I added
another link and everything exploded. I have recently wiped the configs
on all routers and re-did them from scratch. These are very basic configs.
Please let me know if you spot something I've missed.
Thanks once again in advance,
Dave
