Hold that last thought, too early in the morning and not enough coffee
yet....I was wrong in my assumption, cause you would have to change the
BVI interface not the sub....
I will try to test it out, but after thinking about it a few seconds I
stand corrected and take the place of giver of bad information :)

Subject: OSPF p-t-multipoint vs NON-Broadcast interface!
Hello there,
Here is my scenario"
R3
/
NON-Broadcast
/
R2----p-t-m-
\
point-to-multipoint
\
R1
R2's OSPF multipoint interface must be configured as a
multipoint interface. I use Ip ospf network point to
multipoint interface c-d, on R2 and R1, I establish
adj and have identical databes, everything is a OK.
Now
R3 has a multipoint subinterface, network type by
default is NON-Broadcast, I am not allowed to use the
ip ospf network command on R3to change this type. With
a point to miltipoint network type at one end and a
NON-broadcast network type at the other end,
OSPF establishes adj between R2 and R3, but will not
exchange routing tables, the hello/dead/retransmit
timers are identical. I can ping across, but the
routing tables are different, I have 5 OSPF routes on
R2 and 0 routes on R3. R3's interface being a
non-broadcast is looking for a DR, the other side
doesnt use a DR/BDR!!! Apparently this is a normal
behavior. Is there a work around it?
R3
R3#o ne
Neighbor ID Pri State Dead Time
Address Interface
2.2.2.2 10 FULL/DR 00:01:33
120.20.234.2 Serial1/0.23
R3#
On R2
R2#o ne
Neighbor ID Pri State Dead Time
Address Interface
1.1.1.1 0 FULL/ - 00:01:56
120.20.234.4 Serial0/0.234
3.3.3.3 1 FULL/ - 00:01:33
120.20.234.3 Serial0/0.234
R2#
I tried neighbor statements on R2/R3, it doesnt help.
I implemented a GRE tunnel between R2/R3, it didnt
help. Any ideas?? It is much appreciated.
Thank you
Nathasha
