  Hi Ajay,

  Are you running IOS, JunOS, something else ? You could do it
  via Rancid, using *login scripts. But there are ways to do this using SNMP
  and BGP mibs:

  Free BGP4-MIB SNMP MIB Download - Free MIB Download - Search MIBs - OiDViEW
  Cisco

  Note that the network monitoring platform Observium has built-in
  support for tracking BGP sessions.

  Finally, another way to do this that could spare the CPU on on
  your routers if you run this often would be to setup a peer running
  Quagga (or BIRD) on a Linux/BSD host and run the monitoring there.

  Cheers,
  Phil

that will only provide the calculated prefix entries from the RIB, not the
received-routes from each host. I.e. it's not necessarily going to be 100%
accurate.
