The NSX Tier-0 Gateway router must be configured to use its loopback address as the source address for Internal Border Gateway Protocol (IBGP) peering sessions.
Description
Discussion Text
Using a loopback address as the source address offers a multitude of uses for security, access, management, and scalability of the Border Gateway Protocol (BGP) routers. It is easier to construct appropriate ingress filters for router management plane traffic destined to the network management subnet since the source addresses will be from the range used for loopback interfaces instead of a larger range of addresses used for physical interfaces. Log information recorded by authentication and syslog servers will record the router’s loopback address instead of the numerous physical interface addresses.
The routers within the iBGP domain should also use loopback addresses as the source address when establishing BGP sessions.
