The interface numbers can be compared with the output following Figure 25.18, and the IP addresses and subnet masks can be compared with the values output by the ifconfig command in Section 3.8. The next table, Figure 25.23, is the IP routing table. (Recall our description of routing tables in Section 9.2.) The index used to access each row of the table is the destination IP address. Figure 25.24 is the IP routing table on the host sun obtained with the dump ipRouteTable command using snmpi. We have deleted all five of the routing metrics, since they are all -1. In the column headings we've also removed the prefix ipRoute from each variable name. IP routing table, index = < ipRouteDest > Name ipRouteDest Datatype R/W lpAddress * Description Destination IP address. A value of indicates a default entry. * Interface number: ifIndex. ipRouteMetricI INTEGER * Primary routing metric. The meaning of the metric depends on the routing protocol (ipRouteProto). A value of -1 means it's not used. ipRouteMetric2 INTEGER * Alternative routing metric. IpRouteMetric3 INTEGER * Alternative routing metric. IpRouteMetric4 INTEGER * Alternative routing metric. ipRoutelfIndex INTEGER IpRouteNextHop IpAddress * IpRouteType INTEGER * IP address of next-hop router. Route type: 1 = other, 2 = invalidated route, 3 = direct, 4 = indirect. file:///D|/Documents%20and%20Settings/bigini/Doc...omenet2run/tcpip/tcp-ip-illustrated/snmp_sim.htm (20 of 33) [12/09/2001 14.47.40] Chapter 25.
