Verifying the configuration
After enabling IRDP on Host A and Host B, display the routing table for the hosts (Host A for example).
[HostA@localhost ~]$ netstat -rne Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.154.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 0.0.0.0 10.154.5.1 0.0.0.0 UG 0 0 0 eth1
The output shows that the default route on Host A points to IP address 10.154.5.1, and Host A has routes to 192.168.1.0/24 and 192.168.2.0/24.
