Multicast PIM Help

Hey all,

I’m starting a project with multicast and have run into a couple of issues i someone might be able to help me with.

I started off with a 4.10 router and enabled PIM on the local interface, ran a VLC multicast server on it and used clients to grab it which worked and then I moved onto trying 2 routers.

I’m doing this in a live network so have to be carful but i’ve run into an issue with the 2nd router not joining the MCAST group.

“21:49:51 pim,warning JoinDesired(*,G) = true: upstream neighbor for RP xxx.xxx.64.1 for group 224.0.1.20: not found”

The Joins table on the 2nd router is showing 224.0.1.20 (My VLC stream ip) with a blank source, RP = xxx.xxx.64.1, Join State = Joined, Join Register State = Unknown

Any ideas?

The 2nd router has pppoe for its WAN and has a nat’ed 192 range for the client lan, the 1st router is all public ip’s with the VLC box on a public IP aswell. When I try to view the VLC stream I get nothing and no traffic is going to the 2nd router.

Or better yet a full example of Server > R1 > R2 > Client setup? The one on the wiki is either lacking or incorrect

Any luck?

As far as I know, Multicasts do not work over any PPP connection, so using PPPoE to transport Multicasts will not work.
You will probably need an EoIP Tunnel for that.
