An access control list (ACL) is an ordered list of rules used to filter traffic. Each rule states what’s permitted or what’s denied. Here’s a look at how to configure ACLs on Cisco Routers.
Policy-based routing (PBR) is a technique used to make routing decisions based on policies set by network administrators. Here’s a look at how it works and how you can configure it on your network(s).
Access lists, also known as access control lists, are configured on routers and used to regulate traffic entering and exiting networks. Access lists can be configured for all routed network protocols such as IP. Learn more about them and how to configure them!
Hot Standby Router Protocol (HSRP) is an automatic backup system for Cisco systems. Learn how to set up standby groups, configure timers, read an HSRP MAC address, and enable interface tracking and preempt.
Frame relay is a cost-effective way to connect Local Area Networks (LANs) or transport data between endpoints in Wide Area Network (WANs). Learn how frame relays operate and how to configure a Cisco router into a frame relay switch.
Learn about a process that uses routing protocols to help improve accessibility within networks, especially larger networks, in our latest Networking Basics post.
Border Gateway Protocol (BGP) plays a major role in the control you have over navigating your network connection. Even if you never configure a router, you should understand the ins and outs of BGP.
There’s ways to help your network traffic flow more efficiently. Discover how OSPF areas and LSA types play crucial roles in helping improve network performance.
MPLS (Multi-protocol Label Switching) is a protocol-agnostic routing technique designed to speed up and shape traffic flows across wide area- and service provider- networks. Discover how it works — and why it’s important for you to understand.
Wildcard Masks sound like something straight out of an action movie. But they actually play a vital role in controlling traffic across networks. Discover what they are, how they work, and why they are so important.
