[f-nsp] BGP: No path is selected as BEST route

Thu Dec 29 11:04:57 EST 2005

Dear,

After running into a problem with a certain IP not being able to see content in our network, i started to do some testing and I found
that the router doesn't return a path from the BGP table for the destination.

>> SSH at ams-gs-rt1#show ip bgp 82.168.??.??
>> Number of BGP Routes matching display condition : 2
>> Status codes: s suppressed, d damped, h history, * valid, > best, i internal
>> Origin codes: i - IGP, e - EGP, ? - incomplete
>> Network            Next Hop        Metric LocPrf Weight Path
>> *   82.168.0.0/14      84.233.??.??               110    0      8928 1299 3257 5615 i
>> *   82.168.0.0/14      217.170.??.??               90     0     24785 20562 5615 i
>>       No path is selected as BEST route

After some google-ing I found this mailinglist with this problem looking a lot like mine.
This was it's awnser:

>> You may want to take a look at the 'show default values' command to make
>> sure you have enough CAM allocated to the routing tables to support all
>> the routes you have.  The config command 'system-max ip-route' will
>> allow you to change this, but requires a reboot.

This is my "show version" result:

My question:
Do I need to do a software update in able to fix the routing problem?
(Cause I have never done this before and I prefere testing it a bit more before doing it in a live enviroment)

Kind regards,
Armand Krijgsman
