7th Edition - Page 617

[Lion66six]

I'm confused a little by the top of page 617. For people with the 6th edition, its figure 10.2 and the conversations about the Sales / Finance & Marketting LAN.

Page 616 shows us an access list that looks like the following

Lab_A#conf t
Lab_A(config)#access-list 10 deny 172.16.40.0 0.0.0.255
Lab_A(config)#access-list 10 permit any

Thats great. The next page 3rd sentence in then states this :

"At this point, the access list is configured to deny source addresses from the Sales LAN and the Finance LAN and still allow everyone else in".

Question : How is it also blocking the Finance LAN which the figure shows as being on the 172.16.50.0 /24 subnet? I can agree it blocks the Sales LAN as thats the 172.16.40.0 /24 subnet, but not the 172.16.50.0 /24 subnet?? ...

Or have i missed the point?

Okay, I am missing a word here, that's why this sounds wrong:


"At this point, the access list is configured to deny source addresses from the Sales LAN to the Finance LAN and still allow everyone else in".

That makes more sense :-)

Other than that, great book. Really helping me with my studies. In particular the practical lab work for DHCP really helped. I do my training normally through a website, but its examples were not that clear for DHCP. Using your stuff as a guide helped a lot :D

That's great to hear.

I dunno what is up with Cisco, but DHCP is a HUGE objective.
What are we, MCSE's now too? Come on!!
Seriously...weird...

Do as many DHCP labs as possible.
My new 7th edition has a good Packet Tracer DHCP lab...

Cheers!

Maybe they are trying to cover branch (SOHO) as well. I have had to configure a router to be a DHCP server, Firewall, S2S VPN, Remote VPN, Failover router, failover VPN, QOS, QOS VPN, various NAT/PAT/ACL rules - the list just went on and on, and this was for a site with 50 people sat on a ADSL link that gave them no more than 3MB up and 750KBS down!

The poor little standard DRAMM/Flash 1841 was hurting!

Thanks Todd,

I will have a look at the packet tracer DHCP labs later this week, see what they are all about :-)

BigEvil, its like you believe that routers can feel pain ... :p I've asked them, and they can't

[Big Evil]

No i do not "believe" - i know it!! :)
