A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. ... A packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node. We use Cisco to connect our three remote offices using WAN technology. We have put some basic routes on the router to enable failover when a WAN link is down.
- Segments the network.
- Provides security through the use of Access Control Lists.
- Makes routing decisions using routing protocols such as OSPF, RIP, BGP etc ...
- Provides fault tolerance.
- Cisco Routers are more expensive than other competitors.
- Cisco Routers require leaning of the command line interface, complicated stuff for non-technical people.
- Interchangeability is limited with some other manufacturers because Cisco sometimes uses proprietary protocols.
