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.

1) PIM-SM works, we are going to need a bit more data, can we get the output of `show ip multicast` and `show ip pim rp-info` as a start?

2) `terminal monitor` is currently only meant for when you telnet into a particular daemon.  There is no good way to have asynchronous logging data between all the daemons be sent to the vtysh process for what you are trying to do.  I would suggest using a `log file XXX` and in another window tail'ing that file.  I have also been known to turn on debugging, watching the log file via a `tail -f XXXX &` and then invoking vtysh to see output as I do work.

3) this is the same question as #1, so yes.

Hi all,
My name is Tamar and I have the release 5.0.1 of the FRRouting, it is an excellent  IP routing protocol suite!
I try to use frr in multicast traffic.

1)      Is frr support multicast traffic? (I ask because I tried without success)

I write this commands:

ip multicast

ip pim rp IP ADDR

inteface INTERFACE

ip pim sm\\ in all interfaces

                Also I add an ospf:
                                router ospf 1
network 0.0.0.0 0.0.0.0 area 0
                my setup include tow PC and one additional router (VM of cisco)
                This setup does not foreword a multicast traffic unfortunately …

2)      I try to debug the traffic in the frr with the “debug” commands but it does not print to the screen anything.

In the manual

When I wrote the command I got

Why?

3)      Is the frr support pim protocol?
It is written in the manual but not work in my setup

I would be very grateful if you could help me with this.
Thank you!
Tamar
