    Eigrp over NBMA network

    carlos - CCNP, CCSI, CCNA Security

      Hi everyone I got a lab in which I´m using Eigrp over frame-relay multipoint.

      some interfaces are point-to-point.

      What happens is that on the multipoint peers the adjacencies keep failing but one the point to point everything is fine.

      i did a debug and here is the output:

          Router configs for the link on s0/0.1.  Also, is the FRswitch setup correctly?

              how about "show ip eigrp neighbors on multipoint router, and sh run interface <> on sopkes..

               

               

              there are no acknowlwdgements of packte seq no here, in the debug.

              .

              Also, check whether if the  multipoint-int is not configured with "no arp frame-relay"  if not using static assignments on the other routers.

                I managed to solve it but I need some explanation.

                I have to say that before I posted the frame-relay map ip commands did not includ the broadcast keyword.

                just by typing the broadcast keyword the neighbors adjacencies became stable which for me is wierd because

                in my understanding the broadcast keyword is just there to make sure that multipoint interfaces use multicast it has nothing to do with neighbor relationship.

                  Eigrp uses Multicast 224.0.0.10 for its packets, like updates, hello, and  queries (some times). It uses unicast too, that depends, like the acks are always unicasts. All is under the reliable delivery mechanism the eigrp uses.

                  Now, frame-relay don't support the multicast, as the name suggests Non-Broadcast-multiaccess.

                  Using the Broadcast keyword, enables something that works as multicast, but indeed is not multicast. It is unicast but to all DLCIs. Pseudo-broadcast they call it. Replicating the packets for each dlci, thats what it is. (if i get it right :-))

                   

                  Though, you should have posted the actual configs ;-)

                   

                   

                   

                  PS.

                  And yes, keep in mind disabling the splithorizon for spoke to spoke connectivity.

                    Thank you very much Ip4nb.

                    I´ll do some more research on then post the config has it was.

                      another option that you have is to declare your neighbors manually with the neighbor command under the eigrp process, this is because EIGRP split horizon is enable by default on subinterfaces, specially in multipoint subinterfaces. But if you use the neighbor command remember that just only one sentece disables multicast discovery, so the hello packets sends unicast, and you must configure one neighbor sentence for each neighbor.
