[Xorp-users] Problems with mutlicast

[Muzinich, Mike]

I am using the latest code from GIT, I think.  Is there a file I can check to ensure I am using the latest code?

We are having problems getting multicast working through a GRE tunnel. All other traffic passes through the tunnel except for multicast. Both GRE endpoints are
multi-homed. When I generate multicast traffic, I see traffic hit the inside interface but I don't see it hit the outside or tunnel interface. PIM neighbors,
bootstrap, mrib, and rps all look fine but every entry in the mfc table doesn't have an outgoing interface.

I have tried disabling and enabling net.ipv4.conf.default.rp_filter with no change in behavior , routed all multicast traffic through tun0, enabled multicast on
the tunnel interface and gre0, and tried this with and without the outside interface in the Xorp configuration. Most of the warning messages related to the
tunnel are:

[ 2011/12/22 15:18:07.618194 WARNING xorp_pimsm4 PIM ] JoinDesired(S,G) = true: upstream neighbor for source X.X.X.X and group 224.0.1.60: not found

Any help I can get will be appreciated. We are running version 1.8.4.

Use the latest code from GIT...I think I fixed that since the last release.

Thanks,
Ben
