even with a proper extended ping.... even with a reload

i will give u an example...

suppose frame-relay hub and spoke.. R1 R2 R3... R2 is the hub and the RP and
the MP

                                  - - - - -R1
                          - - - -
R2----------------------
                         - - - -
                                 - - - - - R3

now, when i try to ping from R1 to R3 .. the first ping makes it ... but the
rest dont ...!!!

of course nbma mode is enabled on R2...

any explination
