BGP Community output

Hi ,

Turing testing BGP community i found some different output.

I got link for SP & he was advertising community say 2000 & i would like to add more community as it reached to My AS.

So i would like to add two more community say 1000 & 1500 using additive  key word ( which will not overwite but will add it to existing string )

So when i added this community i got output as 1000 1500 2000 in sh ip bgp x.x.x.x .

So why this community is adding before SP community ?

i should see 2000 1000 1500 because the way of adding this community is  SP + 1000 + 1500 .

Hi,

isn't the output just an ascending sequence?

As it should not matter in which order the communities were added, there is just a set of communities.

HTH,

Milan

Thanks For Reply

Actually i would like to know why it is showing me in ascending seq ?

Why it would not show me as i had appened the new community value ?

If i will config any seq with these community then also i get the same output.

Hi,

there is no order in community so it is just how the IOS is displaying it with lowest value first.

Regards.

Alain
