Hi guys!
I've worked with JunOS in the recently past, and now I need to set community at the aggregate prefixes generated, to classify the summary level (based in length mask). I tried to use "attribute-map" unsuccessfully. The IOS is the "L3-ADVENTERPRISE9-15.5.2T.bin" (Cisco IOL).Below the 2 scenarios, where I can successfully set the community using the "Option-2" (using tag feature). How could I use the "attribute-map" to make it? Thanl you in advance.
