[f-nsp] Multiple Internet Providers

Hi Everyone,

I am new to the list and new to configuring multiple internet providers.

We are adding a second internet provider to our BI8000 and I am not able 
to get the routing right.  Everything wants to go out of the default 
route.  How do I need to configure the routing so that when I ping my 
second providers IP on our interface it responds properly?  We have 
several IP ranges, including a /25 that is coming from the first 
provider and we are adding additional /24's coming from our new provider 
and I want to make sure I can route these back to the proper provider.

I think I am missing something simple, but for the life of me I can't 
quite catch it.

I have tried adding an ip policy route-map to the interface but that 
didn't work.  I have tried to add a ip route for the /30 to the second 
provider but it didn't work either.  When I add a second default route 
with a distance of 240 and changed the original default route to 
distance 240 so that BGP takes precedence I see the interface come up 
for about 15 ping responses and then it returns to sending thru the 
default gateway IP.

Any help or suggestions would be greatly appreciated.

Thanks everyone

Joe
