The network administrators use floating static routes to provide a backup path to a primary static or dynamic route, in the event of a link failure. The floating static route works only when the primary route is not available. There may be the primary route fails due to physical layer problems and a wrong configuration, […]
A summary static route can be used to minimize the number of static routes in the routing table. Less routing table entries produce less CPU overhead and also provide better processing speed with faster routing table lookups. Using summary static routes we can also make the management of a large number of static routes easy […]
The figure below illustrates the stub network and a default route connection. The Router0 is a stub router because there is only one path towards a destination network. Any network connected to this router would be a stub network. This means that local network of switch1 is a stub network and Router 1 is a […]
The procedure for transferring data between different networks is called routing. It is the foundation of every data network. The routers are responsible for transferring data from one network to another network. It is learning about remote network using two ways: Static Routing – The network administrator add remote networks manually into the routing table […]
In the earlier period of networking the Layer 2 switch was the fastest devices for forwarding data just like the data is physically received and forward onto other ports and the router was comparatively slow in the process. The network engineer thinks about to extend the switch portion into access, distribution and core layer as […]
The network layer (Layer 3) of the OSI model is responsible for packet forwarding between intermediate routers and different networks. The routers are working in layer 3 of the OSI model, but usually its seen that the routers are considerably slower than layer 2 switches. The layer 2 switches cannot communicate in different networks, because […]
If you are using a legacy Inter-VLAN routing, ensure that switch ports connect to the router interface should be configured in the correct VLAN. This is a very common issue with a switch port and required troubleshooting. If a switch port is not configured to correct VLAN, the devices on that VLAN cannot communicate outside […]
