The community value is still a 32-bit number whether you express it as a single number between 1 and 4.2 billion, or whether you express it in the #:# format.
The binary value is still the same 32-bits in BGP though.

I just can’t get my arms around how to use and implement a community new format number. I’ve looked at Halabi and the BGP section of the TCP/IP book, but can’t find a reasonable amount of information to see how the new format can be implemented. Sounds kinda basic, I know - but when I try it in the lab the route I assign a new-format number to is not advertised to my neighbor. Is there an assumption that when using the new-format numbering the community is also no-export?
Thanks!
