ccnp switch 6.0

The longest match principle is the default route lookup method for CISCO IOS routers. When the router receives an IP packet, it performs bit-bit bit-by -bit lookup between the destination IP address of the packet and the entry in its local routing table until the longest matching entry is found. This is called the longest match. in principle. A CFI of 1 is indicated as a non-classic format. Used to distinguish between Ethernet frames, FDDI ( Fiber Distributed Digital Interface ) frames, and Token Ring frames. Community The network segment of the network local direct interface enters BGP , the MED value is 0 ; the network local static route enters BGP , and the MED value is 0. R4#sh ip b 100.0.1.0 Use set excommunity cost x to set in route-map ? 3 : MD5 verification. 200 Two-way re-release on R2 . Under normal circumstances, R1 can learn 3.3.3.0 , and R3 can learn 1.1.1.0. parameter If the interface is trunk , set the trunk protocol type * i100.0.2.0/24 LocPrf federal technical background VLAN10 , then the SVI interface corresponding to VLAN10 is interface vlan10 or SVI10 . This SVI10 is a Layer 3 interface. You can configure an IP address for this SVI port , which is the same network segment as the IP address of the PC user in VLAN 10 . , VLAN10 users in the gateway will be able to point to this SVI interfaces, when VLAN10 the PC network required to access the network segment outside their data to the gateway, which is SVI10 , and then by the SVI to do routing and data forwarding lookup. In fact,ccnp switch 6.0, in this understanding process, we can route the model to the analogy with one arm.
