[nsp] stupid question

ok, this seems to me to be a very stupid question, but it caused me
to take down part of my network today. network looks like this:
192.168.2.0/24 lan--2600A---t1---2600B--10.0.0.0/8 lan--2924--10.75.1.50
i removed some bgp configs that my predecessor had been experimenting
with, and i could no longer reach 10.75.1.50 in the 10/8 lan. on 2600A, i
have these static routes
ip route 10.0.0.0 255.0.0.0 se0/0 10.1.7.2
ip route 0.0.0.0 0.0.0.0 fas0/0 192.168.5.253 (my firewall)
on the 2600B router, i have these routes
ip route 192.168.2.0 255.255.255.0 se0/0 10.1.7.1
ip route 0.0.0.0 0.0.0.0 se0/0 10.1.7.1
a traceroute during the 'outage' showed that 2600A was trying to dump
the packet out to the firewall, which obviously didn't know what to do
with it...

[etc]
so here is my question - what am i missing? shouldn't a route to 10/8 on
2600A pointing to 2600B be enough?
thanks
