Hi Sadiq,
I am using main interface on all routers with same ip subnet.but not full
mesh
R1 ;-
interface Loopback0

!
interface Serial1/0

hey Mark,
So are you doing a Hub and Spoke setup? If yes, are you using a multipoint
sub interface on the hub or point-to-point sub interfaces?
Is possible, can u sketch something out? - Always helps ppl understand the
topology..
