Yes, assuming the router has multiple physical interfaces or paths to which the loopback can be reached. &nbsp;If the router only has one physical interface or one path to it's neighbor(s), using a loopback doesn't provide any further stability.

Well, certainly true on iBGP connections. eBGP requires connectivity to your peer, and usually this is on a single interface anyway.

I need a clarification to make is it correct to say that use of loopback interfaces as BGP source address is recommended since the loopback interface &nbsp;unlike a physical Interface / subinterface does not go down . As such this reduces the flapping on the BGP tables in the network

Loopback addresses and BGP

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
