During discovery, IP Availability Manager queries every Cisco or Juniper device (router or switch) in the managed network for BGP support.

IP Availability Manager queries a device’s SNMP agent for an additional MIB object named bgpPeerLocalAddr to determine whether the device supports the BGP routing protocol. If bgpPeerLocalAddr exists for the device, IP Availability Manager adds the device to the BGP topology collection set, along with other discovered network objects that are associated with the device.
