Routing update issue

I have an issue that I am spinning my wheels on, help if you can.

here is the lay-out

Internet---Pix1--------CORE Layer 3---------Router 2 Co-Lo------Router at
Co-Lo-----PIX2-----INTERNET


Ok so I have a two site wan, each site has internet connectivity and each
has their own Pix. At the main site the default route on the core points to
the Pix internal. At the Co-Lo site the router default is its local pix.
EIGRP is running on all the internal routers, the core also has a second
static route for 0.0.0.0 0.0.0.0 X.X.X.X 10 (the X.X.X.X is the ip to the
co-lo rotuer). Ok so if I loose my primary pix, or loose my t1 at the
primary site traffic is not being re-routed out the Co-Lo. I tried to get
the pix to broadcast RIP default routes but cannot seem to get the core or
the rotuer at the Co-Lo to recognize.

It's kind of a hard to troubleshoot without configurations (which would
be very usefull) but I will add some inline comments. If that won't give
you an idea how to fix problems, please post configs of routers (without
passwords, ofcourse).

You have a real mess there. First, question would be, how will your
pixes 'know' if your internet connection is dead? Will the ethernet on
outside go down in that case?

Second question would be why not use just one routing protocols on all
routers and pixes? (RIP and OSPF are most likely available). If you use
something like that, you will not need to have static routes at all
(except the default routes on PIXes) and handle traffic direction using
'ospf cost' or RIP hops.

The (at least my) idea of a good design is to keep it as simple as
possible. Again, if you have particular reason why do you want EIGRP and
statics, please post your configs.

hope this help...

P.S. After re-reading my own post I noticed '...no static routes at
all..' statement. This is probably consequence of a CCIE lab exam .

Are RIP routes (default) being redistributed into EIGRP ?


router eigrp #
redistribute rip
exit

I take it that core and the router at your co-lo are running RIP or
having, and are injecting the RIP-discovered routes into the EIGRP process ?

A show run of your config would be helpful

later ..
