[FROG] Multicast Protocol

Wed Oct 24 09:07:37 EDT 2018

The `show ip multicast` command is showing that pim does not think vpp0 or
vpp1 have an ip address or an associated VIFI in the linux kernel.   I
would recommend trying this again:

conf t
interface vpp0
  no ip pim sm
  ip pim sm
!

interface vpp1
  no ip igmp join 224.1.1.1 3.3.3.4
  no ip pim sm
  ip pim sm
  ip igmp join 224.1.1.1 3.3.3.4
!

Then let's re-issue a `show ip multicast` and see if those interfaces are
now configured under pim.  If not we can discuss debugging.

I would also recommend joining the FRRouting slack for a real-time
debugging ability.
