Just a quick note. I do have multicast enabled on the server gre1 interface. A tshark capture shows the igmp group queries from the router and the igmp join reply from the server. On Wed, Jan 9, 2013 at 10:51 AM, Brian Christopher Raaen < mailing-lists@brianraaen.com> wrote:
I am trying to set up multicast between a Linux server and Router using GRE. The GRE tunnel is up fine and I can see traffic go across it, but the router is not indicating it is receiving the IGMP joins that the server is sending. I have identical setting with another server attached to fastethernet0/1 and it is joined to the group fine, but I am not able to get the server to link to the router via GRE interface. Note that I have another server behind another router where the two routers do GRE and PIM and that on is working fine. Is there some reason that IGMP joins would not work across the GRE link, but another router using PIM would?
