Refer to the exhibit. The network consists of hundreds of routers branched from connected regional distribution sites using single area OSPF.

- Adopt RIPv2 which is not subject to packet flooding.
- Implement static routing.
- Implement a mix of routing protocols to contain the instabilities.
- Change the topology to a heirarchical design which puts each branch network in its own area.
