Why is the response of the NBSP;OSPF show command very slow? What is the purpose of the clear IP OSPF redistribution command? Does NBSP;OSPF cause neighbors that are not in the same subnet to form adjacencies? How long does NBSP;OSPF send a link state advertisement (LSA)?

Cisco is now the world's largest manufacturer of switching routes! Many of our businesses, large and small, can use the network, and it is possible to switch routes to Cisco! When we install network equipment, we may ask the network engineer to help us install it! Access to the router has a lot of passwords! What if we forget these passwords? We may have to make changes to the routing entries when our compa

Now that Cisco Nat is flexible, Can Linux implement it? The answer is yes! Linux netfilter is super flexible, and Linux Nat is not flexible because the iptables program is not flexible. xtables-Addons rawnat has taken an important step towards static Nat, iptables restricts the development of static Nat in Linux! So I put aside iptables, first implemented the kernel module based on Netfilter, and then used procfs as the user interface to see how to im
