Multicast: IGMP v2 Join (*,G) or Shared Route Tree entry?

(michael m) #1

Hi All,

I’m getting a bit confused by some outputs on the show ip mroute command.

When i have a multicast source trying to join a group, the router connected to the host shows an entry in the form of (*,G).

But I’m also reading PIM Sparse mode uses Shared Tree format of (*,G), where * is a wilcard mask meaning all sources.

I’m confused as to when the (*,G) entry is being used as IGMP v2 join or Shared Tree entry.

thanks in advance for any anwsers. Mutlicast takes some learning.
