Each router running RIP manages a routing database that contains routing entries to all reachable destinations on the network. These routing entries contain the following information: CISCO default MED is 0 The AVG is responsible for responding to the ARP request of the PC to the gateway , while the AVG is responsible for the allocation of the virtual MAC . AVG can be flexible depending on the load balancing mode PC 's ARP request response. Experimental example: Calling in the distribution list Preference , will trigger Notifacation message , causing session interruption; but can use IN on AS border router Basic VLAN communication principle r route is not loaded into the RIB table, for example due to AD values, etc. Path Control Overview , By the spanning tree protocol in a particular port logically Block , in order to achieve redundant physical environment, and the upper floor and preventing the loops ? 100 8.3.4 Questions 104 The longest match The description of several fields ( ISL header) in the above figure is as follows: The first 8 bits of the route must match the first 8 bits of 172.0.0.0 , the other bits are not concerned, and the mask must be /8 . So looking at the above picture, two VLANs are created on the Layer 3 switch : 10 and 20 ,ccnp r&s logo, and the addresses of the SVIs of the two VLANs are assigned as the user gateways of the respective VLANs , so that the routing table of the switch is There are routes for two VLAN segments. Then, when the two VLANs need to communicate with each other, the user of VLAN 10 will drop the data to his own gateway, that is , the SVI of VLAN 10. After the data arrives at SVI10 , the Layer 3 switch looks up the table and finds that the destination is the network segment where VLAN 20 is located. Throw the data out of VLAN 20 and eventually reach the destination VLAN 20 of the PC .
