- All link state advertisements begin with a common 20 byte header this header contains enough information to uniquely identify the advertisements link state type link state id and advertising router multiple instances of the link state advertisement may exist in the routing domain at the same time it is then necessary to determine which instance is more recent this is accomplished by examining the link state age link state sequence number and link state checksum fields that are also contained in the link state advertisement header 178

- Class a subnet masks 200
- Classless inter domain routing cidr 200
- D link des 3326sr layer 3 switch 200
- Multiplying the number of subnets times the number of nodes gives 12 582 900 possible nodes 200
- Note that this is less than the 16 777 214 possible nodes that an unsubnetted class a network would have 200
- Subnetting reduces the number of possible nodes for a given network but increases the segmentation of the network 200
- Under cidr the subnet mask notation is reduced to a simplified shorthand instead of specifying all of the bits of the subnet mask it is simply listed as the number of contiguous 1 s bits in the network portion of the address look at the subnet mask of the above example in binary 11111111 1100000 0000000 0000000 and you can see that there are 11 1 s or 11 bits used to mask the network address from the node address written in cidr notation this becomes 10 2 11 200
