Re: Add communities on direct routes in Juniper

[Saku Ytti <saku () ytti fi>]

Unfortunately not yet, as far as I know. Long time ago I gave this to
my account team

Title:     Direct routes must support tag and or community
Platform:  Trio, priority MX80, MPC2
JunOS:     12.4Rx
Command:   'set interfaxe ge-4/2.0 family inet address 10.42.42.1/24
tag|community X'
JTAC:      n/a
ER:
  - Router must be able to add tags communities to direct routes directly, like
    it does for static routes

Usage Case:
  Trivial way to signal route information to BGP. Often tag/community is used
  by service providers to singal 'this is PI/PA prefix, leak it to internet' or
  'this is backup route, reduce its MED'. However for some reason it is only
  supported for static routes, while usage scenario and benefits are exactly the
  same for direct routes.
