PIM over Frame-relay

Unanswered Question
Mar 1st, 2007

I cannot get PIM to establish neighborship over Frame-relay in p-t-mp network. What is necessary to get it working? "ip pim nbma-mode" interface command does not seem to help.

interface Serial6/7:0.2 multipoint

ip address

ip pim nbma-mode

ip pim sparse-mode

ip ospf network broadcast

ip ospf priority 50

ntp broadcast

frame-relay interface-dlci 144

frame-relay interface-dlci 145

R1#sh ip pim interface

Address Interface Ver/ Nbr Query DR DR

Mode Count Intvl Prior Serial6/7:0.2 v2/S 0 30 1

I have this problem too.

I tried all kinds of things (like disabling InARP and introducing static DLCI-IP mapping) and at some point PIM started to work over the FR cloud. I then tried to revert the configuration to the original (non-working) state, but PIM still works. I have no idea what was different.
