RPF failures on multicast over gre tunnel
Hi Rich,
You only have a recursion risk when you have a dynamic routing protocol advertising the other end of the tunnel and as such, you get into a situation when the tunnel is advertised via the physical and the physical is advertised via the tunnel as well, and it gets all complicated.
But in this situation, the ends of the tunnel are almost directly connected. I said almost because there is a FR switch between. But from the IP layer’s perspective, they are.
