I was able to add ordinary communities to l2vpn NLRIs via vrf-export
policy attached to routing-instance to allow them later pass route
reflector's policies. The small caveat is that vrf-export overrides
default policy generated by vrf-target and both communities (target:x:x
and ASN:x) must be _added_ in the policy but it's documented pretty
clear. May be it will work this way for evpn as well.
WBR,

Does anyone know if it is possible and how to add communities to
routes to
an EVPN routing-instance in the instance configuration itself? For
example,
in bgp.evpn.0, I have
2:a.b.c.d:200::1900::00:1f:45:a0:1b:bb/304 (2 entries, 0 announced)
...
Communities: target:64900:200
I'd like to be able to add, for example, $MYISP:12345 to the mac
announcements. I haven't tried but am guessing I could do this in
the IBGP
export policy using 'from instance' but this is suboptimal because
then my PE
will need different export policies whereas they are currently now
all
congruent.
Very interesting question indeed,
and I believe it's valid requirement as well.
I'm just trying to find out, to no avail, if one can control what MAC
addresses make it from MAC address table to MP-BGP and with what
attributes.
If such a policy attachment point would exist one could tag MAC
addresses with standard communities there (but I think no such thing
exist in Junos or XR)
So when you tried to tag the MAC routes using iBGP peer export policy
-has that worked please?
