config problem on serial interfaces

totts

Can anyone spot this problem I've created. The serial interfaces have been working ok then I tinkered... swapped the back-to-back cables around and changed the ip addresses... pretty innocent stuff. Basically the networks set up like this...

NY S0 LONDON S0
192.192.192.1/27 > 192.192.192.2/27
DCE


NY S1 LONDON S1
192.192.192.33/27 > 192.192.192.34/27
DCE

I've put the cables back, checked the ip addressing scheme, checked I've
set 'bandwidth 64000' on the correct DCE side, carried out 'no shutdown' on
the interfaces countless times, tried pinging, re-typed in the ip addresses on
the interfaces, reloaded the routers, configured ip routing (but don't think I
need to on back-to-back).

I know its probably something simple, but see what you think.

I havent looked too deep into the show commands you posted but a quick thing to check is keepalives... make sure they are the same. Default is 10seconds.... I will keep looking at your config and post what I come up with... you can see the keepalives with "show interface serial #"
