WebWe will use the loopback interface as the source for our BGP session. Why? A physical interface can go down which means the IP address on the interface is no longer reachable. A loopback interface will never go down unless the router crashes or when you “shut” it. This is why it’s best practice to use loopback interfaces when configuring IBGP.
