The Traceroute program can be used to check if routing in the intranet is
symmetric for each source-destination pair. Use the –g loose source routing
option as shown in the following command syntax:
Richardson3% traceroute -g santa_clara_itg4 richardson3
The Traceroute program identifies the intranet links that transmit IP Trunk
3.01 (and later) traffic. For example, if Traceroute of four site pairs yield
the results shown in Table 21 "Traceroute identification of intranet links"
(page 124), then the load of IP Trunk 3.01 (and later) traffic per link can be
computed as shown in Table 22 "Route link traffic estimation" (page 124).
