OSPF router is a kind of agreement, it's called open shortest path first (OSPF), is a standard type LS routing protocol to relay topology, but the amount of resources is more, the agreement number is 89, cisco has not publicly EIGRP technology, so the OSPF show is very important, for its working process, use the group broadcast to send hello to confirm all the neighbors, if received the hello packets containing their routing id neighbor neighbor relationship with each other, and generate the neighbor table, and then the conditions of matching in the neighbor table, stay here, if the match failure keep alive keep only 10 s of the cycle, after the success of the match, using DBD/LSR/LSU LSACK to obtain the unknown LAS information, is completed, leave in for 10 s keep alive, when configure OSPF, to pay attention to the division of OSPF and its inverse mask, regional division has two rules, it is a must have area 0, 0 and area and other areas must be connected directly, the second is must have the ARB is called area border router, boundary router is according to a router two ports, one side is the backbone area, namely 0 area, other area on one side, the writing of the mask the mask of 0 (IP addresses as immutable, instead of 1 is variable if the declaration is an accurate address, while the mask can be written as 0.0.0.0 if the range for a network can be written as 0.0.0.255 like this, as long as proclaimed by address range, you can find it,
