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
