if i have a router, lets call it Router A, connected to 3 sites using frame relay.
each with different subnet,then i have 3 subinterfaces configured as point-to-point subintefaces. we can picture this as hub and spoke.
can i replace these 3 subinterfaces(Router A) as multipoint.
if the answer is yes, this lead to my next question :
1.what is the difference between that two configurations?
2.do you think point-to-point become useless ? since it can be replaced by multipoint ?
or maybe each subinterface configured require more memory/cpu processing of the router ?
