Detailed rules Fast Switching Routing Protocols In a route-map statement, if there is no match statement, match all Port Metric The IGP routes into BGP when the associated Route-map settings RIP secondary address problem Cc00.043c.0000 (10.1.1.253) local R4 selects R5 as the next hop to the 100 network segment. This is because the two routes are taken from R5 , the weight weight is 100 , and the weight of R3 is the default 0. Naturally, R5 is preferred,ccnp tshoot study, so R4 will The path is switched to R5 . When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. When a bridge starts to active, each port sends a BPDU every 2s , and when a port receives a better BPDU than the one sent now , the local port will stop sending if it is within a certain period of time ( But after saving for 20s ), he no longer receives better from neighbors. V2 defaults to send v2 to receive v2 length Use a hold-down timer to prevent routing loops First come to know the first three-layer interface: SVI switched virtual interface, a logical interface of SVI , that is to say not a physical interface, when we create a VLAN on the switch , we can create a The SVI interface corresponding to the VLAN , for example, we created Relevant points Router(config)#router rip Metric LocPrf Weight Suboption type Switchport mode access switchport port-security We know that in a campus network, the largest number of devices should generally be switches (Layer 2 and Layer 3 switches), of which the number of Layer 2 switches is mostly. The Layer 2 switches are in a typical Layer 3 network structure. At the "access layer", the main task is to provide access to the PCs and users of the terminal , and to divide the VLAN isolation broadcast domain, and then run STP to provide a Layer 2 anti-ring mechanism. A small and medium-sized campus network, the number of two-layer switches is often hundreds. These devices are usually unpacked at the customer site, and are usually commissioned by engineers on the site with a console cable.
