PBR is a packet routing and forwarding process that allows a router to determine how packets passing through it are handled based on a route map. The route map decides the next-hop forwarding router for a packet. Generally, enabling dynamic routing protocols on a router to dynamically learn the network topology may cause devices within the network to dynamically …
VLAN assignment based on switch ports is the most widely used and most effective method. Currently, the vast majority of switches supporting VLAN protocols offer this VLAN configuration method. This VLAN assignment method is based on the Ethernet switch鈥檚 physical ports, grouping the physical ports on the VLAN switch and the internal PVC ports of the VLAN switch into…
Dual-router cascading involves connecting two routers (referred to as A and B below) via an Ethernet cable. This is typically done when the LAN ports on a single device are insufficient (mainstream models only have 4 ports) and you need to connect multiple routers to share the same public network or LAN.

A link refers to the physical circuit between a node and an adjacent node. It relies on the physical layer to provide data transmission and reception services, while offering the network layer functions such as data packet encapsulation and network layer parameter negotiation. The sender and receiver determine the information necessary for data transmission by exchanging LCP packets. 1. …
Similar to how ARP viruses often manifest as direct attacks on internet cafes, causing frequent disconnections for users, solving network attacks has become a hot topic for internet cafes. Internet cafe switches can identify, block, limit, and log ARP attack and DDoS attack events. When purchasing switches for an internet cafe, you need to buy products capable of solving network attacks…
For network devices, clearing configuration information is the best way to prevent hackers from easily accessing the corporate network. Today, I’ll show you how to clean up internal data on routers and switches. When wiping a Cisco router, there are two different methods to choose from, and they are typically used for different …
Since campus networks have IPv6, but most current low-end routers don’t support IPv6 implementation well, you can’t use IPv6 when accessing the internet through router NAT. That said, there’s still a workaround — configure the router to act as a switch through specific settings. The method is: 1. Set the IP address of the router’s LAN port …
