Multicast- OSPF neighbor in Init state

Hi Everyone,

I am having this problem of establishing OSPF adj. between R2 and R5 over a
FR Cloud. The 2 neighbors are always stuck in a INIT state.

This started when I configured multicast - ip pim sparse-dense-mode - on
the multipoint serial interfaces.

If I remove the 'ip pim sparse-dense-mode' the neighbors will revert back to
a FULL state.

I tried using 'ip pim nbma-mode' to no avail. Anyway the IOS complains the
nbma-mode is not recommended for sparse-dense-mode.

Any help appreciated.

Thanks,

Paul
