and Network+ Tip: "Attenuation" is the gradual weakening of an electric signal as it travels. That's why repeaters were developed back in the day - these devices send a clear and strong copy of an incoming signal. Repeaters work at OSI Layer 1.

Let's start today with a quick review of important RAM / ROM / Flash / NVRAM info!

ROM: Read-Only Memory. ROM stores the switch’s bootstrap startup program, operating system software, and power-on diagnostic programs (POSTs). ROM content is retained on reload.

Flash memory: Generally referred to simply as “flash”, you’ll find IOS images here. Flash is erasable and reprogrammable ROM. Flash content is retained on a reload.

RAM: Random-Access Memory. Stores operational information such as routing and switching tables and the running configuration file. RAM contents are lost when the router is powered down or reloaded.

NVRAM: Non-Volatile RAM. NVRAM holds the router’s startup configuration file. NVRAM contents are not lost on a reload.

Coming In April 2020!

#CCNA Tip Time!

You can use "show ip ospf neighbor" to verify an OSPF virtual link. No DR or BDR for that adjacency, though, as shown here.

Also note the interface type "OSPF_VL0" -- that's another small hint you're looking at a virtual link. : )

2020-01-10T11:44:00.000-05:00

CCNA Tip Time!

When you change a router's OSPF RID, you have to do one of two things to make that change take effect:

1. Reload the router

2. Clear the OSPF process

The router will remind you of this, as shown here. The exam will not. : )

#CCNA Tip:

Even if a Cisco switch hasn't learned any MAC addresses dynamically AND you haven't entered any static entries, its MAC address table isn't quite empty.

In this case, there are 20 other entries -- all for the CPU. Good stuff to know. : )

See you later today with another handy CCNA tip!
