How to monitor the route link(BGP) in which interface port status might be up but BGP link is down and traffic getting routed through another route link?

SapphireIMS supports BGP link monitoring which identifies the BGP peer status( route link status). This may be needed when routes are getting failed frequently though interface is up.

SapphireIMS uses BGP4-MIB OIDs using SNMP to monitor the BGP links and following parameters are getting collected.

bgpPeerIdentifier 1.3.6.1.2.1.15.3.1.1
bgpPeerState 1.3.6.1.2.1.15.3.1.2
bgpPeerLocalAddr 1.3.6.1.2.1.15.3.1.5
bgpPeerRemoteAddr 1.3.6.1.2.1.15.3.1.7

The alerts can be set to notify when the BGP peer status is up or down based on the requirement.
