BGP PIC Fundamentals: BGP PIC ( Prefix Independent Convergence ) is a BGP Fast reroute mechanism which can provides sub second convergence even for the 800K internet prefixes by taking help of IGP convergence.
I would like to share with you every week some networking resources , can be video , article , book , diagram , another website etc. Whatever I believe can be useful for the computer network engineers, mobile network providers, satellite engineers ,transmission experts, datacenter engineers, basically whatever I am interested in and I like, …
BGP Best External is used in Active Standby BGP Topologies generally but not limited with that.BGP Best External feature helps BGP to converge much faster by sending external BGP prefixes which wouldn’t normally be sent if they are not overall BGP best path.
BGP Next-hop behaviour – One of my CCDE bootcamp students asked a question about next hop in MPLS VPN network. So, I would be very pleased to explain the BGP next hop behaviour both in IP and MPLS network in this post.
Settlement-Free Peering Requirements.
Unique RD per PE per VRF is a deployment option in MPLS Layer 3 VPN.
BGP PIC Edge provides sub second convergence time in the case of edge link or node failure. BGP PIC is a useful for MPLS VPN service and can be provided by the Service provider as a value added service thus might provide additional revenue.
BGP Route Reflector in Plain English, in this post, I will explain you the BGP Route Reflector basics, after you read this post, you will be able to answer many questions regarding BGP Route Reflectors. I am explaining this topic in deep detail in my Onsite CCDE , Live/Webex CCDE , Self Paced CCDE and …
BGP Route Reflector Clusters – BGP route reflectors, used as an alternate method to full mesh IBGP, help in scaling. BGP route reflector cluster is used to provide redundancy in a BGP RR design. BGP Route reflectors and RR clients create a cluster. (Cluster = BGP RR + BGP RR Clients)
BGP Optimal Route Reflection provides Optimal Routing for the Route Reflector Clients without sending all available paths.
