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 .
