[j-nsp] Multicast - interop with Cisco

[Stacy W. Smith]

Auto-RP requires groups 224.0.1.39/32 and 224.0.1.40/32 to operate in dense mode. That operation is not automatic in JunOS; it must be configured.

Add this to your config:

[edit protocols pim]
user at host# set dense-groups 224.0.1.39/32
user at host# set dense-groups 224.0.1.40/32
