Hello,

is there a way to have OpenBGPD matching more than one BGP community in
a single statement?

I need to perform some actions only when 2 or more communities are
simultaneously attached to a route.

I've tried the following statements but all failed:

# syntax error
match from any community 1:2 3:4 set community 5:6
match from any community 1:2, 3:4 set community 5:6
match from any community {1:2 3:4} set community 5:6
match from any community {1:2, 3:4} set community 5:6

# "community" already specified
match from any community 1:2 community 3:4 set community 5:6

Thanks
