[f-nsp] Route Not Entering Routing Table

Hi Jeroen,

Yeah, we have two different provider uplinks and we will be adding at 
least one more in the coming future.

When I do a sh int e 1/1 it is showing up/up.  I also checked to make 
sure the media was compatible.  LH on Level3 side and LX on my side.  I 
have had the Fiber tested between their equipment and mine and it is 
good.  I would think a hardware issue, but when I make a change, such as 
remove and re-add "gig-default neg-off" or remove and re-add the "ip 
route 0.0.0.0 0.0.0.0 4.53.232.89 distance 240" the interface starts 
pinging for a minute or two and then stops responding.  So for some 
reason it is not being added to my routing table.  I have a J-BxGMR 
management card with 512M ram, here is my output of 'sh ver':

When I do a "sh ip route static" only the 70.42.176.196/30 shows up, not 
my other route.  I removed and re-added the IP information for the 
Interface and also removed and re-added the ip route for that interface 
several times last night.  Including moving the connection to port 1/3 
and also 3/1.  Both of which responded for a minute or two before 
stopping again.

I am very confused as to why it is doing this and am hoping someone 
knows of a reason or a guess why when adding a new interface to the 
BI8000 it might not be added to the routing table right.  I would not 
think it would be this hard to add an interface to a router.

Thanks

Joe
