IPv6 OSPF/v3: Case Study
This document is an illustration of Stub, Totally Stub and NSSA area feature in an IPv6 environment. Stub, NSSA, and totally stubby are supported and configured in the exact same way as for OSPFv2 for IPv4, using the area stub, area nssa, and area stub...
OSPF Neighborship Troubleshooting
When setting up dynamic routing protocols, there are certainly a number of things that need to be configured correctly for everything to end up working as planned. On top of this, each of the different routing protocols has different elements that they...
the Difference between a Layer-3 Switch and a Router
In general, a Layer-3 switch (routing switch) is primarily a switch (a Layer-2 device) that has been enhanced or taught some routing (Layer 3) capabilities. A router is a Layer-3 device that simply does routing only. In the case of a switching router,...
