Again, I'm continuing a review of previous Cisco modules. In CCNA 2, Chapter 220.127.116.11, it states,
A common configuration in many networks is to have a static default route on the edge router forwarding packets to the ISP. The ISP router then has a static route pointing to the customer's network.
For example, Customer A has the network address of 172.16.0.0/16, which is subnetted into several /24 subnets. The edge router of Customer A has a static default route forwarding all other traffic to the ISP router:
ip route 0.0.0.0 0.0.0.0 serial 0/0/0
The ISP router has a static default route for forwarding traffic to Customer A's network:
ip route 172.16.0.0 255.255.0.0 serial 0/0/1
Is 172.16.0.0 255.255.0.0 really a static default route? I know it is a static route, but a static default route? I thought all static default routes had an IP and subnet mask of 0.0.0.0 0.0.0.0.
