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. R2(config)# router ospf 1 This address of the neighbor must be IP reachable (Note that in the actual environment, the situation may be quite different). The above interface loses the portfast and bpdufilter features immediately after receiving the BPDU , and becomes an ordinary spanning-tree interface. Interface vlan 10 Reposted FAQ 49 100 The two exchange modes , both in principle and in terms of fast switching is very similar , such as optimum switching actually uses an optimized cache switching (optimumed switching cache),ccnp switch study guide, its speed is higher than usual cache is faster .distributed switching mode needs use Versatile Interface card this hardware card , also known as the VIP card. it will save a copy of their own route cache, so that when it is not necessary to wait for a query using a shared system cache (shared system buffer), whether with respect to the fast switching or optimum In terms of switching , it is faster .
