SDM allows you to configure static routes and common dynamic routing protocols, such as OSPF, RIP 2nd, and VPN. Now, using Cisco SDM, QoS policies can be easily applied to any WAN or VPN channel interface.

Technical principle: OSPD Open Shortest Path priority protocol. is one of the most widely used routing protocols in the current network. belongs to the internal network routing protocol. Being able to adapt to network environments of all sizes is a typical link-state protocol. The OSPF routing protocol spreads the link state information of the device to the whole network, so that each device in the net finally synchronizes a database with the whole ne

OSPF is also known as the interface status routing protocol. It establishes a link status database by notifying the status of network interfaces between routers to generate a shortest path tree. Each OSPF router uses these Shortest Paths to construct a route table, OSPF will send a HELLO packet on the network. If there
