I'm experiencing problems to get work multiple multipoint GRE interfaces on a 7204VXR router acting as Hub.
When I configure one multipoint GRE interface, it works and every spoke can establish a IPsec tunnel with the HUB. But when I configure 2 multipoint GRE interfaces on the HUB, the first multipoint GRE is always matched. And the spoke can be associated on the wrong multipoint GRE interface.
Is there a way to solve the problem ? Or I am wrong
