Note, that the peer should be configured accordingly in order BGP to work.
Attention! In this scenario the router has no input or output filters configured. This means that it can
redistribute lots of unnecessary or harmful information to its peers. Always consider configuring
proper routing filters before you configure BGP peering.

Description
The Border Gateway Protocol (BGP) is the core routing protocol of the Internet. It maintains a table
of routes 'prefixes', which specify network layer reachability information (NLRI) between
autonomous systems (AS). BGP is described as path vector protocol or policy routing protocol,
referring to the way it chooses the best route towards destination. Unlike many other routing
protocols, BGP does not use technical metrics to select the best path but rather administrative
policies. The current version of BGP, Border Gateway Protocol 4, is specified in RFC 1771.
The routes learned by BGP protocol are installed in the route list with the distance of 200 for iBGP
(Internal BGP) routes and of 20 for eBGP (External BGP) routes.
