OSPF is a link-state routing protocol。It is designed to be run internal to a single __（71）__system。Each OSPF router maintains an identical __（72）__ describing the autonomous system’s topology。From this database，a routing table is calculated by constructing a shortest-path __（73）__。OSPF recalculates routes quickly in the face of topological changes，utilizing a minimum of routing __（74）__ traffic。OSPF provides support for equal-cost multipath。An area routing capability is provided，enabling an additional level of routing protection and a reduction in routing protocol__（75）__。

Serialization delay, i.e. the amount of time it takes to put the （72） on the wire, and queuing delay (depth of the queue) are improved by increasing the （73） from a 128Kbps circuit to a T1. However, three other components of delay, routing/switching delay, distance delay, and protocol delay are components that can not be positively affected by an （74） in bandwidth.

    ●One ofthe main resposibilities ofICMP is to report (71). Although technology has produced increasingly reliable transmission media, errors still exist and must be handled. IP is an (72) protocol. This means that error checking and error control are not a concem ofIP.ICMP was designed, in part, to compensate for this shortcoming. Howerver, ICMP does not _(73) errors, it simply reports them. Error correction is left to the higher-level potocols. Error messages are always sent to the original__(74) because the only information available in the datagram about the route is the source and destination lP addresses.
