Thanks a lot for your feedback.

of course I used source x.x.x.x

My question was/is

Is it the absolutely necessity
to activate PIM on an interface which
will be used for igmp join-group ?

In "legacy" IGMPv2 I was able to
ping to an loopback interface w/o Active PIM
(but only from 1 "hop distance").

Is it a general or just best practice ?

Pls any comments

=======================================

You need to add

int fa 0/0
ip pim sparse-mode
ip pim igmp version 3
ip igmp join-group 239.50.50.50 source 1.1.1.1

You need to mention the source in the igmp version 3.

Thanks,

Anees.

Hi GS,

testing PIM SSM by means of DYNAMIPS and trying
to verify the "best config" for PIM SSM

R4 ----- PIM SM ----- R1 ----- PIM SM ----- R2

all routers with PIM SM & PIM SSM DEF

R2 has Loopbacks with IP IGMP v3 & JOING-GROUPs 232.x.x.x

==>> It was not possible to ping w/o PIM activation on Loopbacks

Who could confirm this behavior based on REAL gears ?

Moreover, for usual IGMPv2 groups on R2 (with AutoRP listener)
it was possible to ping loopback-groups (239.y.y.y) from R1 only.
From R4 solid pings are possible only to the groups on a Loopback
with active PIM SM!

Is that a "hop" problem ?
