Help Routing Trouble!

I have a some problems I can't sort out.
I have 1 sendmail server linked to a swich. I also have 2 other cisco routers linked to this switch. The cisco routers talk to other buildings/states.

I have several problems:
1) I don't understand why I can't ping my cisco router. Although I can't ping my cisco router I can ping through my cisco router to get to other states/buildings. I can only do this by manually adding route add -net 10.0.0.0 255.255.255 gw 10.10.10.10 metric 3. I had to do this to ping to other network linked to the router 10.10.10.10.

2)I don't understand why on my IP routing table I have 2 occurances of a.b.c.d1 as a gateway. Whereelse to I need to edit aside from ../ifcfg-eh1 and eth0? I have .../network stop and started several times without success. I still get multiple occurances.

3)Consider site A and B. I can ping from linux box A to Desktop B with latency <60ms however when pinging from B to A latency is >200ms. Why would this occur?

See the /../ifcfg-eth1 and eth0 below also see route -v

Any help is greatly appreciated

eth0:

eth1:
