[Xorp-users] Help : Test setup for Pim4 and IGMP between sunets (for VLC source and Receiver ) multicast test.

[saurabh]

Dear Xorp users,

 

"I think many of other xorp users must passed this stage, at where I am
struggling right now" 

I am struggling to make the test setup of pim and igmp (after going thru
manuals and rfcs)

 

Aim is to see multicast traffic in VLC player at PC1 which is coming from
PC2 (multicast source for 224.0.0.4)

,Off course through PIM and IGMP. (I should see proper join & prune at both
routers) 

 

I have two pc(win-xp),  (At diff subnets)

two routers (both run Xorp live cd). 

 

With 2nd XP pc2, I am multicasting stream at 224.0.0.4 group..udp(port
1234).. 

And @ 1st xp pc1, I am trying to view the video stream. 

 

Both Pcs are behind different xorp (live cd) router as shown in figure
below..

 

PC1 -xp                                      PC2 -xp

193.193.193.111                       194.194.194.111        

     eth(0)                                          (eth0)

            |                                             |     

            |                                             |    

    le1 193.193.193.1        le1 194.194.194.1    (pim-RP) (DR)

    le0 195.195.195.20     le0 195.195.195.10              

  XORP-CD-Router1 ----  XORP-CD-Router2

 

 

(bsd naming are le0..1 ..instead of eth0.1..)

 

IGMP activity is happening: (:-))

What I observed is that PC1's vlc client is joining 224.0.0.4 group, when I
start to

Play button of vlc,  I can see it by "show igmp group" command at router1's
cli, 

 

No PIM activity is happening: (:-()

I noted that router1 is not sending pim join (*,G) to router2 for group
224.0.0.4 

(Which should be as I have defined router1's le0 as RP for group
224.0.0.4/8)

 

Only I can see pim neighbors while trying command ("show pim neighbors"), in
both

routers , in that case router1 is being shown as NOT DR, and router2 as DR

 

And I have also noted that multicast traffic that is coming at le1 in
router2, 

(from PC2-which is multicast source)  that is not forwarded to le0. 

(I think which should be, as it must go to RP interface which is le0 of
router2) ! 

 

Plese help me, what I missing something? 

 

I have configured fib2mrib.. And not configured any other unicast protocols.
(Is this correct)

I have also not set default gateway (default routes in any routers)

 

 

I think "Mohd" and other users have done this setup that I saw from
sep-oct-2009 mailing list? 

 

Plese share your exp. for pim igmp setup.. 

 

 

config are below,,,,

 

 

Thanks,

Saurabh

 

config file for router2 i given here in last, in router1 config only change 

in interface address, remaining all are same
