[c-nsp] EIGRP Routes dropping out of topology table within MPLS VPN

Mon Oct 23 04:37:47 EDT 2006

Hello Eric .

Can you provide the " show ip route vrf xxx " output please ? 

Is this showing the route is actually learn via BGP or EIGRP ? 

Can you provide as well " show ip bgp vpnv4 vrf xxxx | inc  <your route> 

A sample of the running config will be awesome as well .

[c-nsp] EIGRP Routes dropping out of topology table within MPLS VPN

I have a situation where a customer is running EIGRP within an MPLS VPN.
They will call that a site is "down" and when we issue a 'show ip eigrp 
vrf
xx top'  the routes are not in there. If you check 'show ip route vrf xx'
they are there.  (I can post with sample tables if necessary).  If I reset
the BGP sessions with the route reflector, they all come back.

I have tried 2 different routers, reboots, IOS upgrades, etc  to no avail.
The strange thing is I did an IOS upgrade last night and after the reboot
there were only 21 routes in the top table after thereboot instead of 62. 
I
had to clear the BGP sessions right after the reboot ???

show vers below of the routers - have tried 12.3(19)P, 12.3(20)P,
12.2.18S12P
I can't find any direct bug notices either ??

Anyone seen anything like this ?  We had them on a 7500 a while back and
never had a problem.

Thanks
Eric
