Listing all "multipath" routes

Marek Manik
Level 1
Level 1

Hi all,

i would like to check if it is worth enabling "maximum-path ibgp XY". I have ASR9K running 5.3.3.

I would like to check how many prefixes meet all criteria for ibgp multipath. (I assume there should not be that many, because it depends on topology and all path for particular prefix have to have the same BGP attributes including the same IGP cost to next hop and next hop have to be different )

Is there any command which can list all prefixes flagged with "multipath"? (Or at least how many they are.)

Thanks

marek

Thnx samallis,

but if I have full RT how can I list those which has "multipath" set? I can't check every prefix.

At least to know how many they are will still be enough. I didn't find any command for that.

I was also looking for any indirect way to check that. Can I simply rely on count in "sh route ipv4/6 summary"? If I have 50K routes candidates for "multipath", I should be able to see it.

There is no significant difference in "sh route ipv4/6 summary" if I enable it or not. So, I'm not so sure if I don't have that many multipath routes or I'm looking at wrong place.

thnx

MM
