Configure the router in a Hub & Spoke manner using IP addressing and DLCI information given in above diagram.
R1 - This router should use DLCIs 102, 103 & 104 for it's connection to R2, R3 and R4 respectively. This router should be configured in a multipoint manner.
R2, R3 & R4 - DLCIs 201, 301 & 401 should be used by R2, R3 and R4 respectively for their Frame-Relay connection to R1.
Ensure that these routers have full reachability to every loopback interface, this should include their own interface too.
Restrictions - 1.) You are not allowed to user " frame-relay map ip ", and/or static/dynamic routing to accomplish this task.
2.) None Of the routers should be configured with sub-interfaces/s.
