ccna dumps practice

When the router performs a classless route lookup (by default, ip classless ), it does not pay attention to the class of the destination address. It performs the longest match between the destination address and all known routes bit by bit . Interface FastEthernet1/0 When debugging , you can open debug ipv6 nd 200::/7 is reserved for the network service access point NSAP . Currently, the NSAP reserved space is not used . The NSAP address is mainly used in the ATM technology. On R2 , in order to reach the network connected by R1 , R2 configures a tool that uses route summarization, referring to a summary route: 192.168.0.0/16 to R1 , although this does serve the purpose of network optimization, but this summary route Too "rough",ccna dumps practice, it even includes the network segment on the R3 side, we call this behavior not accurate enough. Therefore, an ideal way is to use a "just right" summary route that includes these detailed routes, so that you can avoid the problem of insufficient aggregation.
