Image 202 * 172.16.0.0/16 is variably subnetted, 4 subnets, 2 masks S* 172.16.0.0/16 [1/0] via 172.16.3.0 Next Hop They will be written in binary form, in fact, we only consider a third 8 bit group can be, because it is the only change As OSPF2 create a route in the static summary routes ( the Null0 ), and static routes redistributed into OSPF1 modified OSPF1 administrative distance, the OSPF1 priority than OSPF2 administrative distance Requested node multicast address Solicited-node Image Protocol ID: 0x0800 1/8 Look at the above picture, the gray space 172.16.0.0/16 , this network number, we call the main class network number , the so-called main class network number,ccna dumps online free, meaning the network number, according to the IP address category to which it belongs , corresponding to The network number obtained after the default subnet mask length. Such as 172.16.0.0 this is a CE1 and CE2 configuration Router(config-router)# area area-id range xxxxx CE1 and CE2 configuration Class and classless route lookup The configuration of R2 is as follows: Ipv6 access-list ipv6only-network permit 2001:1::/64 any 0000 010x xxxx xxxx Extended header Last read 00:00:44, last write 00:00:47, hold time is 180, keepalive interval is 60 seconds Neighbor capabilities: Local site address (Site-local address) !! NET entity address The router goes to update the route of 3.0.0.0 At this point , the route 1.1.1.0 is seen on R3 , which contains the next hop attribute, and the previous one. 3 jumps. Configure RIP unicast updates: Access-list 1 permit 1.1.1.0 Ipv6 router rip RIPprocess exit Protocol ID: 0x0800 Ipv6 nd ra-interval or Experimental steps and configuration In this mode, a data flow (Flow) in the first packet (Packet) will be placed into the cache system (system buffer). The destination address to the routing table will get a match query , the processing of the router device (CPU or Processer) while for CRC check , check whether the packet correctly . then Layer packet MAC address will be rewritten , replaced by the next-hop interface MAC address, this process will continue , for this data flow (flow) in the first 2 th, . 3 packets ...... same operation , comprising a routing table is rewritten MAC address , CRC checking. This method is undoubtedly the most delayed , because it uses the system buffer and processor to process each received packet .But we still have the opportunity to use this type of exchange , such as when performing load balancing based on each package , or when debugging ip packets .
