  4. Isn’t IPSec tunnel mode not supporting multicast?

    How does EIGRP establishes neighborship within these routers?

  5. Hello Ray

    It is true that IPsec alone does not support multicast. However, if you want to create an EIGRP neighbourship over IPsec, you must run a GRE tunnel in conjunction with IPsec. GRE supports multicast so this would solve the problem.

    Another option is to use an EIGRP static neighbour. This automatically makes EIGRP use only unicast for communication between neighbours.

    I hope this has been helpful!
