Hi

With OSPF point-to-multipoint, host routes (/32) are learned by each spoke
router for the other spokes.

Regards,
Justin

Subject: FRAME RELAY AND IP OSPF NETWORK POINT-TO-MULTIPOINT HELP

Hello - I'm just trying to clarify something with this command. This is
Frame Relay. In a partial mesh between 3 routers. One router is the hub and
all routers have the ip ospf point-to-multipoint configured on a
sub-interface. The subinterface on each spoke have a map statement assigning
the hub ip address to its DLCI. There is no map statement for the ip of the
other spoke on either spoke. The hub has map statements for both spokes. How
does the spoke know what layer 3 to layer 2 map to use when pinging to the
other spoke if there is no manual map configured? Why does this work when
network type point-to-multipoint is configured and not when network type
broadcast is configured? Does the spoke just send the packet out on the dlci
that is mapped to the hub IP and hope the hub has the map?

Thanks,

Jason Wydra
