In this video, Todd Lammle will discuss the access-lists covered in the latest Cisco Certified Entry Network Technician (CCENT) objectives regarding security. Access-list, specifically names and numbers standard access-lists will be demonstrated and verified with the most common verification commands used with access-list. Finally, comparing standard and extended access-lists in a lab is shown.
- [Narrator] Now that we have an understanding of…standard access lists and how we can configure them…with both named and numbered access lists,…let's run out to San Francisco…and demonstrate how we can stop the corp router…from telnetting into San Francisco…by using a named standard access list.…Let's take a look.…The first thing I want to as Corp…is I'm gonna ping corp 10.2…and telnet to Corp or San Francisco from Corp.…All right, looking good, and we'll get back out.…And let's run out.…
I wanna call (mumbles) San Francisco…because I'm gonna block Corp.…So I'm gonna say config T.…Now I can type access list and use a numbered access list…for standard B1 to 99.…We also have 13 to 1999, we usually don't use those.…You don't usually use standard access list really,…but IP that's the (mumbles) objective.…IP access list standard.…So we're using a named.…I'm gonna call this Block Corp.…
Nice, okay.…Not much we can do here, guys,…with the standard access list.…Block the source, right?…So I'm gonna say deny host 172.16.10.1.…
