Information
If the set community rt and soo are in the same route-map entry, the behavior defines as:
● If the rt option comes before soo, with or without the additive option, soo overrides the
communities rt sets.
● If the rt option comes after soo, without the additive option, rt overrides the communities soo
sets.
● If the rt with the additive option comes after soo, rt adds the communities soo sets.
