So what you are saying is that the canonical representation of a single Large Community value is three unsigned decimal integer values, separated by a ‘:’ (colon) character, representing the value as a triplet of unsigned 32-bit integer values. Implementations SHOULD accept this representation as a valid form of representation of the value of a Large Community.
