In a multipoint interface, you need something to map L3 to L2 reachability. In ethernet, we have ARP to do that for us. In frame-relay, we have either Inverse-ARP (on by default, but likely disabled in the lab) or we have static mapping. But this MUST be done, or we have no reachability and therefore can't encapsulate! Cheers,

In the meantime I thank you everyone for support. ----- Original message ----- From: "Scott Morris" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED], [email protected] Date: Sat, 16 Feb 2008 20:04:09 -0500 Subject: RE: [OSL | CCIE_RS] Frame-Relay Try looking at the output of "debug ip packet" as you do the various pings! That may help highlight the missing piece there from pinging yourself versus the other devices!
