Navigating Legacy Cisco Certifications: A Deep Dive into CBT Nuggets CCIP BGP (642-661) with Jeremy Cioara
Unlike internal protocols that rely purely on basic metrics like bandwidth or delay, BGP uses a strict list of architectural attributes to choose the best route. Cioara's course meticulously visualizes how a router evaluates these variables: (Cisco proprietary, local to the router) cbt nuggets cisco ccip bgp 642661 by jeremy cioara work
The course started by establishing why BGP is different from interior gateway protocols (IGPs) like OSPF or EIGRP. Cioara explained the concept of Autonomous Systems (AS) and how BGP acts as the "glue" holding the global internet together. Viewers learned the mechanics of establishing neighbor relationships, the BGP state machine (Idle, Connect, Active, OpenSent, OpenConfirm, Established), and the crucial differences between Internal BGP (iBGP) and External BGP (eBGP). 2.
