Protocol. Advertising a default route and undoing a static route is important, but hardly everything a network administrator needs to know in order to maintain enterprise networks and autonomous systems. If you're looking for a more in-depth understanding of BGP configuration, try ourBGP training...
Optional transitive: Signifying a transitive attribute between ASs, it is carried in messages even if a BGP device doesn't support it, advertising the information to other peers. Optional non-transitive: If a BGP device doesn't support this attribute, it ignores it and doesn't advertise message...
Brief on MetalLB, BGP and BFD Some concepts have to be conveyed in order to follow the subsequent sections where I will walk through the environment and the configuration procedure. First and foremost, I need to address what MetalLB is. MetalLB is an open source project that provides the ab...
Figure1: A BGP Hijack occurs when a network announces IP-prefixes that do not belong to them, which may circumvent the path to the actual destination. Each network on the internet that participates in BGP is represented by an Autonomous System Number (ASN), which is a n...

BGP works by allowing a network — typically ISPs, but also corporations that connect to more than one ISP — to advertise which public IP address blocks or prefixes they are responsible for to their peers. Critical to this process is the ASN (Autonomous System Number) that identifies each ...
For a Connect attachment, routes in the route table associated with the Connect attachment are advertised to the third-party virtual appliances, such as SD-WAN appliances, running in a VPC through BGP.
