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:
http://www.oidview.com/mibs/0/BGP4-MIB.html
http://tools.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&step=2&mibName=CISCO-BGP4-MIB
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
