What are linux dynamic routing

Linux dynamic routing includes: 1. OSPF, a link state routing protocol, used to calculate and select the shortest path in large networks; 2. BGP, a path vector routing protocol, commonly used on the Internet The interconnection of routes between autonomous systems; 3. RIP, a distance vector routing protocol, used for routing in small networks; 4. IS-IS, a link state routing protocol, usually used in ISP internal networks and LAN routing.

In Linux, there are several common dynamic routing protocols that can be used to implement dynamic routing. Here are some of them:

1. OSPF (Open Shortest Path First) : OSPF is a link state routing protocol used for calculation and selection in large networks shortest path. It builds the network topology by exchanging link status information and calculates the shortest path using Dijkstra's algorithm.

2. BGP (Border Gateway Protocol) : BGP is a path vector routing protocol, usually used for routing interconnection between autonomous systems in the Internet. BGP is widely used for connections between Internet backbone routers.

3. RIP (Routing Information Protocol) : RIP is a distance vector routing protocol used for routing in small networks. It uses hop count as a metric to select paths based on distance.

4. IS-IS (Intermediate System to Intermediate System): IS-IS is a link state routing protocol, similar to OSPF, used for medium and large network. IS-IS is typically used for routing within ISP internal networks and LANs.

Please note that these are just some common examples of dynamic routing protocols in Linux systems. The choice of which protocol to use depends on network size, needs and other relevant factors. Before implementing dynamic routing, carefully study and understand how the chosen protocol works and the configuration requirements, and ensure compatibility with the relevant equipment.
