I am trying to understand setting up policies on a juniper router. What is the difference between "add" and "set" community?
set policy-options policy-statement MY_POLICY term MY_TERM then community ?
<community_name> Name to identify a BGP community
+ Add BGP communities to the route
- Remove BGP communities from the route
= Set the BGP communities in the route
add Add BGP communities to the route
delete Remove BGP communities from the route
set Set the BGP communities in the route
