What Is ACLs? Access Control Lists (ACLs) are a set of rules used in networking to control the flow of traffic into and out of network devices like routers and switches. These rules determine which packets (small units of data) are allowed or denied passage through a network interface. ACLs are crucial for network security and traffic management.… Read More »
Troubleshooting Access Control List (ACL) errors. Using the show commands reveals most of the more common ACL errors before they cause problems in your network. When you look at an ACL configuration, check it against known rules you learned regarding how to build ACLs correctly. Most errors occur because these basic rules are ignored. The most common errors are entering ACL… Read More »
Understanding the Border Gateway Protocol (BGP) The Border Gateway Protocol (BGP) is a sophisticated and advanced distance-vector routing protocol, often categorized as an Exterior Gateway Protocol (EGP). In various sectors, it has earned the moniker of the “big dog” of internet protocols. Interaction Between Autonomous Systems BGP facilitates the exchange of routing information between different Autonomous Systems (ASs).… Read More »
How To Authenticate MD5 for BGP Peers. BGP (Border Gateway Protocol) Peers MD5 Authentication is a security feature used in BGP, the protocol that manages how packets are routed across the internet through different networks (autonomous systems). This feature enhances security by establishing a secure connection between BGP peers (routers) using MD5 (Message Digest 5) hashing. Key Points… Read More »
The Border Gateway Protocol (BGP) is a complex, advanced distance routing protocol utilized primarily for exchanging routing information between major Internet Service Providers (ISPs) and larger client sites. It uses the Best Path Selection Algorithm to choose efficient routes, supporting the complexity of the public internet.
