Folks,
  I have noticed that we can use physical and sub-interface to provide the
service in frame-relay at the same time. Something likes below. So my
curious is that if question asking to have non-broadcast to one subnet and
p-t-p to anther subnet on the hub router. Should we use the configuration as
in ex 1 or ex 2?
How is the difference between these two config?

I have made up the example below up but didn't check if it correct,
apoligize. Just show for the idea.

### Example 1 ###
interface s0/0
encap frame
ip address 1.1.1.1 255.255.255.0
no frame invert
frame map ip 1.1.1.2 102 broad
frame map ip 1.1.1.3 103 broad

interface s0/0.1 point-to-point
ip address 2.2.2.1 255.255.255.0
frame interface-dlc 202

### Example 2 ###
interface s0/0
encap frame
no frame inver
interface s0/0.1 multi
ip address 1.1.1.1 255.255.255.0
bla bla bla
interface s0/0.2 point-to-point
ip address 2.2.2.1 255.255.255.0
bla bla bla

Thanks,
Montiean
