I have R2, R5 and R6 in a frame-relay mesh config.

R2 has a multipoint subinterface to the cloud, R5 and R6 have physical
interfaces.
Inverse-arp is disabled.
R2 has a backup interface to R5 via s0/2/0.

From what I understand of mulitpoint interfaces, is that if I shut R5 and R6
main interfaces down, then R2 will put it's multipoint subinterface in
down/down state. Is that correct?

I even removed frame-maps and ip address off of R2, but the primary
interface is still up/up:

R2(config-subif)#do show ip int brief
Serial0/1/0.256 unassigned YES unset up
up
Serial0/2/0 150.100.25.2 YES NVRAM standby mode
down

R5(config-if)#do show ip int brief | inc 0/1/0
Serial0/1/0 150.100.100.5 YES manual administratively down
down

R6(config-if)#do show ip int brief | inc 0/1/0
Serial0/1/0 150.100.100.6 YES manual administratively down
down

Is there something else I am missing?

Thanks,
