All things related to multicast

[Matthew Davy <>]

On Abilene, we see a couple of MSDP SA's, one from an Arizona host and 
one from a Nysernet host...

 show msdp source-active group 233.26.42.10
Group address   Source address  Peer address    Originator      Flags
233.26.42.10    150.135.75.71   192.80.43.21    192.80.43.21    Accept

We have an NLRI=multicast route to the Arizona RP (192.80.43.21), but 
do not have one for the source IP (150.135.75.71)...

mpd@DNVRng-re0>
 show route table inet.2 192.80.43.21

inet.2: 4880 destinations, 9732 routes (4880 active, 0 holddown, 0 
hidden)
+ = Active Route, - = Last Active, * = Both

As Bill Owens pointed out, the Juniper's will only RPF check against 
the inet.2 (ie multicast) RIB and not the inet.0 unicast RIB.   
Originating a MBGP route for 150.135/16 should fix this.
