When you permit Reverse Route Forwarding (RPF) on an interface, the router will verify with a lookup in the FIB/CEF table to see that there exists a route back again to the resource deal with on the interface on which it receives a packet. This avoids spoofing of packets.
A whole lot of networks leak delicate information and facts on their switchports, this should be a fairly silent switchport.
Cisco Certifications For Networking Authorities

State-of-the-art Switch Simulation Available In Cisco Packet Tracer
Packet Tracer is a routing and switching emulator distributed by Cisco totally free of cost. It is capable of emulating moderately complicated routing and switching scenarios and is fantastic for pupils studying for their CCNA. Although it does not present all the BGP instructions for the CCNP supplied by GNS3 and Dynamips, It has one highly precious characteristic over these applications, it supports level two and three switching simulation, with devices like the 2950 and 3560 as properly as generic unit that makes it possible for the user to generate products with other interfaces these kinds of as the NM-1FFE and NM-1FGE. It supports a relatively broad variety of commands permitting the consumer to establish really sophisticated switching scenarios. I have finished numerous switching lab with EtherChannel, VTP, MLS, and a lot more. Although you are unable to apply some qualities like HSRP, Packet Tracer is by far the very best swap emulator readily available exterior of obtaining actual hardware, and not like GNS3 and Dynamips you do not have to get Cisco IOS's to use it.
Packet Tracer can also be utilised for the CCNA Voice and Wireless Practice labs as it also involves the Cisco 7960 IP mobile phone and wireless routing devices.
