Configuring BGP Peerings Using Loopback Interfaces

This tutorial will explain how to configure BGP peerings between routers using the loopback interfaces. I also explain why a specific command is needed in your configuration in order for this to work. And why your BGP Peering will not form if you fail to configure this one command.
You tyipcally configure peerings with loopback addresses when you're dealing with iBGP. Typically, you're running some type of IGP like OSPF in your network and you advertise the loopback into OSPF. The peer will typically have multiple ways of reaching your loopback. So even if the primary path fails, you have a backup path which means you won't lose the TCP connection to the router. And your BGP peering will not tear down.

Thank you so much buddy. I was facing the same problem and I was not able to identify the problem because it was in idle state. Even i capture the packet. After watching your video it resolved my issue. :)

Does this essentially disable Nat for the source or is there something else going on

My IOS version don't have the update-source parameter on BGP Router config. Perharps it's an old one.
