Next Hop Ip address 10.1.34.4 255.255.255.0 Metric Authentication Type Then, if an OSPF process (this sentence may not be rigorous, everyone understands what I mean), the route can not be summarized, such as the following figure. The KEEPALIVE message actually compensates for the defect that TCP cannot confirm the peer's survival. Lab 2 : The access switch is plugged into option82 and the core switch is relayed. Reference material 100 i 1 OK , now go back to the main class network number 172.16.0.0/16 , then we will go out and look at the picture. 172.0.0.0/8 actually shifts the mask of this class B address to the left by 8 bits , so that the network number obtained is actually a large network number including 172.16.0.0/16 . Call it supernet . Show ip dhcp binding Show dhcp binding on DHCP server After 10.1.31.0 is passed to R2 , since R2 takes the mask of the receiving interface and finds that 10.1.31.0 has a position of 1 in the host part , the subnet is stored in the routing table and treated as a host route. : 10.1.31.0/32 BGP decision Open Shortest Path First (OSPF) Routing Information Protocol (RIP) Route map reference We spotted FIG, R1 and R2 between runs RIP to exchange routing information,ccnp switch experience, R2 by RIP learned the R1 release over 192.168.1.0/24 and 2.0 / 24 routing information loaded into the routing table, labeled R & lt . While R2 and R3 and running OSPF , establish OSPF adjacency, R2 also from R3 , by OSPF learned the two routes: 3.0 and 4.0 / 24 , is also loaded into the routing table, labeled O . So, for R2 , it has its own route to the whole network, but inside R2 , we can understand this : it will not change the route learned from RIP .The OSPF route is told to R3 , and the route learned from OSPF is not sent to R1 as a RIP route . For R2 , although there is complete routing information in its own routing table, it is as if there is a gap between the entries of R and O , which cannot be exceeded.
