15. How DVMRP Chooses a Route Each DVMRP interface is configured with a metric that indicates the cost of the hop A router that receives multiple route reports for the same multicasting source network e Compares the cost specified in each based on the metric field e Stores information from the report with the lowest cost in its routing table A route metric is the sum of all the interface hop metrics from a given route source to a given router In Figure 4 1 on page 4 3 for example router D receives two reports for the network connected to multicasting router A one from router B and one from router C Using the metrics contained in the route reports router D determines that the cost of the tunneled route is greater than the cost of the route that uses direct physical connections Router D discards the route received from router C and stores the route received from router B Router D then declares router B to be the next hop neighbor and interface d1 to be the next hop interface After a next hop neighbor has been declared for a route the route updates received from that neighbor for that route take precedence until either the route times out or until another router advertises a better metric for that route 117355 C Rev 00 Configuring IP Multicasting and Multimedia Services Routing Table Table 4 1 shows the principal items in a routing table entry Table 4 1 Parts of a Routing Table Entry Item Description S
