Just a quick question, if i have a community string from an ISP that will prepend my route, if i set that community 3 times will it prepend it 3 times?
xx:2200 prepend to peers (ISP XX )
if i set community on 188.8.131.52/24 xx:2200, xx:2200, xx:2200 would most ISPs prepend it 3 times?
You can't set the same community more than once for given prefix. On the other hand, the ISP usually provides different communities to prepend the aspath a different number of time.
xxx:2201 = prepend once, xxx:2202 = prepend twice and so on.
