Discussion
Using a loopback address as the source address offers a multitude of uses for security, access, management, and scalability. It is easier to construct appropriate filters for control plane traffic. Log information recorded by authentication and syslog servers will record the router's loopback address instead of the numerous physical interface addresses.
Fix Text
Configure the network device's loopback address as the source address for iBGP peering.
Check Content
Review the configuration and verify iBGP peering uses the devices loopback interface address as the source address. If the loopback interface isn't being used as the source address for iBGP peering, this is a finding.
