Computer Weekly: Static routing for Cisco users [Day Two: The good and bad of static routing]
Don't be fooled into thinking that static routing is always the best tool for the job, however. The greatest negative to using static routes is that they don't scale as your network grows. This is ...
Static routing for Cisco users [Day Two: The good and bad of static routing]
The router will choose a source IP address by doing a recursive lookup against the routing table to see which interface is closest to the destination. The h323-id (case sensitive) command configures ...
I'm looking into securing some switches and routers and I came upon a Cisco guide on hardening IOS devices. In it they have a section on locking down switches with Port ACLs and VLAN Access Maps. I ...
What is routing? Learn how IP routing works, the definition of 'router,' what routing protocols are used on the Internet, and more.
The routing process starts when software on a host device uses a packet's contents, destination, or purpose to select a possible route from a routing table. A routing table is a repository of all the routes to all the destinations in use by a network.
To provide connectivity between networks, routers must learn all network paths, select a single best path to each destination, and add the chosen path to the routing table. You can manually configure these paths on all routers or use a routing protocol.
Routers examine destination addresses, consult their routing tables, and forward packets hop by hop until they reach the right network. Understanding how this process works – and which protocols automate it – is foundational knowledge for anyone managing networks.
