you might want to start with a good monitoring software like Argus - 
http://argus.tcp4me.com/

Group "Upstream Connections" {
   Group "T3 to whomever" {
     Service Ping {
       hostname: far-side.example.net
     }
     Service UDP/SNMP {
       eqvalue: 6
       label: BGP
       uname: BGP
       oid:   .1.3.6.1.2.1.15.3.1.2.x.x.x.x
       hostname: your-router.example.net
     }
   }
   Group "T3 to whomever2" {
     Service Ping {
       hostname: far-other-side.example.net
     }
     Service UDP/SNMP {
       eqvalue: 6
       label: BGP
       uname: BGP
       oid:   .1.3.6.1.2.1.15.3.1.2.x.x.x.x
       hostname: your-router.example.net
     }
   }
}

something like that will alert you when BGP is anything other than 
happy.  your oid may vary.  use snmpwalk to help.

then you could also add:
  Service Prog {
    frequency: 1800
    command: chkbgp.pl -a <ASN> -n <network> -r <route_server>
    nexepect: evil
  }
