Configuring LAN and WAN Interfaces
and Verifying a Router Application SDM
The aboriginal footfall is to set an IP abode on the F0/0 interface of the router I am application (named R3).
I acclimated a crossover cable to affix my PC anon to the f0/0 port.
Now aback I appetite to set up the router with security, I acquire to configure the router aback to
the branch defaults. I can do this via the CLI aloof as I showed you aback at the alpha of this
chapter, but it’s absolutely a accomplished lot easier to do this application SDM!
Using HTTP, I am able to admission the R3 router, go to the Configure page, and acquire Additional
Tasks. Then, I aloof clicked Agreement Management and Reset to Branch Default.
I clicked the Reset Router button in the bottom-right bend and again configured my PC
using the admonition apparent on the awning aloof shown.
Again, application HTTPS, I affiliated to SDM application the 10.10.10.1 abode that was provided
in the directions. SDM had me log in alert with the username cisco as able-bodied as a password
of cisco. I again had to acquire the affidavit from the router, and I’m acceptable to go with a secure
connection.
The Create New Connection button took me to the WAN Wizard.
I was again able to acquire my interface; again I clicked Next.
I again chose High-Level Data Link Control and clicked Next.
I was again able to add my IP abode and mask.
IP Unnumbered is absolutely an absorbing agreement because it lets you set up a network
connection after application an IP address. Instead, you “borrow” an IP abode from another
active interface. This comes in accessible if you appear to be a bit abbreviate on subnets!
Anyway, the abutting awning asked whether I capital to set up changeless acquisition and NAT. Again,
this is article I’ll get into added later, so we’re not activity to configure it aloof yet.
Moving on, I clicked Abutting and accustomed a arbitrary of my consecutive 0/0/1 configuration.
I clicked Finish, and the commands were uploaded to my R3 router. (I’m activity to configure
both the F0/0 and F0/1 interfaces the aforementioned way.)
After allotment the FastEthernet 0/1 interface from the aforementioned area from area I started
to configure the s0/0/1 interface. I chose Create New Connection and was taken to the LAN
Wizard.
The LAN Wizard allows you to either acquire beeline acquisition (which is what we appetite to do
here) or configure 802.1Q trunking. I configured the IP abode and affectation and again clicked Next.
What’s air-conditioned about the SDM at this point is that it would body a DHCP server for this LAN
if I capital it too. Man, this is easy.
Since I accidentally entered the amiss IP abode for F0/1, the alone way to change it now
is to acquire Configure and Edit Interface/Connection in the SDM or use the CLI.
From here, I can double-click the FastEthernet 0/1 interface and change the IP address.
After application the LAN Wizard to set up F0/0, I had to save the agreement and again reconfigure
my PC into the appropriate arrangement and reconnect to SDM to verify my configuration.
We’re good—R3 is now configured! Even admitting my animate and VTY countersign get configured
automatically back I set up the user todd, I still had to acquire Configure and then
Additional Tasks and again Router Properties to set the hostname and accredit abstruse password.
