hi,
so think about two different bier domains at an asbr.
one is over igp1, the other is over igp2.
the asbr is there to interconnect the domains.

that is clear that the fact that the pim join came
in as bier encapsulated indicates that ihe asbr
have to deal with it. anyway i do not suggest
to do it other ways, so keep the requirement
to bier encap the tunneled joins - just set
the destination to the loopback ip.

because further processing of the pim packet have to
find out the bier domain, where the join came from.
this is where unicasting comes in: one can set up
lo1 for igp1 and lo2 for igp2, and pim can simply
guess the domain based on which interface was
addressed.
bfir (or bit set in bitstring) in the bier header
is useless since there could be collisions between
the domains.
source ip is another option, but that may or may not
have bfr id advertised to.
and the last one is the ingress interface of the bier
packet, but in the arch, it is said that bier domain
not have to be contiguous, so there may be
bier-on-the-stick implementations, so this is also
not 100% solution.

regards,
cs

> the stuff works as written in the draft, but the draft does not say anything about what's the bier encapsulated join's destination ip address. i've tried to leave it as is now, multicast, but then changed to unicast of the remote pe's loopback address. both versions works, but the latter helps the remote pe to distinguish between tunneled and normal pim joins, and helps to dispatch the tunneled join to the correct interface. imagine if the remote pe have more loopbacks in different bier domains...
