The first gif has a= tunnel to node 2.=20 Node two has one gif with a tunnel to node 1 configured. If I start a mul= ticast ping from=20 node 2 to the inner address of node 1 gif0, everything is fine. If I then= bring down gif2 on node 1, the ping receives no more responses. The down gif should have no= effect on the ping. Has anyone seen this problem ? What's going on ? Is this a known= bug ? Thanks, Rick
