Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure

Tags: color-o switch test one-arm routing access via interface implementation representationTo achieve inter-VLAN communication, in addition to configuring the SVI interface on the switch, you can also implement VLAN data forwarding by configuring sub-interfaces under the physical interface of the router.Configuration ideas:1 The access switch configures the corresponding VLAN and sets the access PC port to access mode2 Setting the physical interface

Learning Network 4--vlan routing via Cisco emulator Cisco PACKET Tracer

Through the previous experiment we learned that by configuring VLANs, the terminals under different VLANs could not communicate with each other, but if you wanted to communicate between different VLANs, you would need to configure inter-VLAN routingLayer three switches have the capability of the network layer and can be forwarded via the routing functionNetwork environment1 set the IP address and gateway of the terminal ( and, r

Cisco Learning note--BGP14-strip routing principle

BGP is a path vector routing protocol, which is to exchange routing information between autonomous systems in order to discover the most efficient way to access data somewhere on the Internet. How do I choose the best path for routing? The Cisco borderless network reveals the BGP 14 route selection principles for us:BG
