Refer to the exhibit. Internet access is crucial for the company network shown. Internet access is provided by two ISPs. ISP1 is the primary provider and ISP2 is the backup provider. The network administrator configures BorderR as the border router so that in normal operations, all Internet traffic goes through ISP1. However, if the link to ISP1 fails, then BorderR will automatically forward Internet traffic to ISP2. The administrator configures two default routes: However, when the administrator issued the show ip route command to verify the configuration, only the second default route is in the routing table. Why is the first default route not showing?

Refer to the exhibit. Internet access is crucial for the company network shown. Internet access is provided by two ISPs. ISP1 is the primary provider and ISP2 is the backup provider. The network administrator configures BorderR as the border router so that in normal operations, all Internet traffic goes through ISP1. However, if the link to ISP1 fails, then BorderR will automatically forward Internet traffic to ISP2. The administrator configures two default routes:

BorderR(config)# ip route 0.0.0.0 0.0.0.0 192.168.100.1 200
BorderR(config)# ip route 0.0.0.0 0.0.0.0 172.16.1.1

However, when the administrator issued the show ip route command to verify the configuration, only the second default route is in the routing table. Why is the first default route not showing?

  • The first configuration command overwrites the second command.
  • The first default route will be installed into the routing table if there is traffic with an IP address that is destined for the 192.168.100.0 network.
  • This is expected because the link to ISP1 is active. If the link to ISP1 goes down, then the first default route will be installed into the routing table.
  • The first default route cannot be installed into the routing table unless the administrator manually disables the second default route with the no ip route 0.0.0.0 0.0.0.0 172.16.1.1 command.
