Internal BGP Tuning: Mesh Peering to Avoid Loop
In BGP (Border Gateway Protocol), mesh peering is a configuration in which all routers in an autonomous system (AS) are connected to each other via BGP peering sessions. This type of configuration can be used to improve the stability and reliability of the BGP network, as well as to reduce the risk of routing loops. […]
BGP Tuning: Peer with Loopback
BGP (Border Gateway Protocol) is a routing protocol used to exchange routing and reachability information among routers in the Internet. One technique that is often used in BGP tuning is to configure BGP peers to use loopback interfaces. A loopback interface is a virtual interface that is used to create a logical loopback connection to […]
BGP Security Tuning: Pull-up Route
Pull-up routes are a technique used in BGP (Border Gateway Protocol) to prevent routing loops. When a BGP router receives a route from one of its neighbors, it will “pull up” the route and compare it to the routes already in its routing table. If the new route is better than the existing routes, the […]
BGP Troubleshooting: Route Origin
BGP (Border Gateway Protocol) is a routing protocol used to exchange routing and reachability information among routers in the Internet. When troubleshooting BGP issues, one thing to consider is the route origin. BGP routes can be either internal or external. Internal routes are those that originate from within the autonomous system (AS), while external routes […]
