I have a number of nodes on a lan served by a 2900 switch and
2600 router. Most of these nodes have both routable and non-routable ip in the 10.x.x.x range. The router is, of course, the gateway and has a routable IP. Is it possible with either the switch or the router to recognize and associate a non-routable IP with the routable IP of the router? If so, how would I go about this? Tom
Tom, I believe what you mean to say by "routable" and "non-routable" is that the router has both private (RFC: 1918) and public address on it.
In that case, what you're looking for is NAT. Here's one way to do this: 1. Configure the interface that has the private address as the "inside" interface. 2. Configure the other interface (the one that has the public address) as the outside interface. 3. Create an ACL that identifies what "inside" addresses should be translated to the "outside" address. 4. Assosiate that ACL with a NAT statement that causes the router to perform the NAT
=========================== Here's a configuration EXAMPLE: ===========================
interface FastEthernet0/0 description OUTSIDE INTERFACE TO THE INTERNET ip address 22.214.171.124 255.255.255.252 !
Thanks, this is not an area in which I have a lot of familiarity. I have a spare router that I can test it out on, and following your advice I did the first part, but ran into trouble on inside part.
csco(config)#int eth 0/0 csco(config-if)#description OUTSIDE INTERFACE TO THE INTERNET csco(config-if)#ip address 206.55.xxx.xxx 255.255.255.240 csco(config-if)#ip access-group 101 in csco(config-if)#no ip unreachables csco(config-if)#no cdp enable csco(config-if)#ip nat outside csco(config-if)#exit csco(config)#int eth 0/1 ^ % Invalid input detected at '^' marker.
Here is the output from one of my 2600's that has a NM-1FE-TX

In IOS configuration mode you can you remove a command by placing no in front, so
enable conf t no ip name-server 126.96.36.199 no ip name-server 188.8.131.52 ip name server
There are global commands, interface commands and routing process commands
The "ip nameserver" command is an example of a global command
int eth 0/0 description OUTSIDE INTERFACE TO THE INTERNET ip address 206.55.xxx.xxx 255.255.255.240 ip access-group 101 in no ip unreachables no ip proxy-arp no ip redirects no cdp enable ip nat outside exit

There -is- such a feature, but it gives undiscounted prices.
scroll down to the bottom of the page, and click on "Login to SCC". When prompted, log in with your regular support contract username and password. Then, on the tab across the top, click on "PRICING & AVAILABILITY".
On the page that appears, select the service level (e.g., 24x7x4), and the country. If you are selecting anything other than NBD (Next Business Day) then if you are in Canada or USA, be sure to enter your location details, or else the tool will complain.
Below the location details, put in the product code and the date range.
There is a lookup tool if you do not know the magic product code. Unfortunately the lookup tool can be somewhat dense at times; you might have to phrase your search in a number of different ways for it to find your product.
Cisco *does* sell contracts for arbitrary periods -- you could buy
217 days of support from them if you had reason to. Random quotes you get from the online stores will almost always be for 1 year, sometimes 3 years; a Silver partner should be able to get an arbitrary-period quote for you, but in my experience it takes a Gold partner to generate such a quote directly.
If I understand correctly, if you are a Gold or Silver partner, or a big company that buys from Cisco directly, then the prices quoted by the SCC tool will reflect your Cisco discounts. The prices will seldom, however, reflect any government or academic discounts you might be entitled to, and you can often get *much* better pricing by going to a Gold or Silver partner. All authorized Cisco VARs get some level of discount, but they vary in how much of that discount they will pass on to you. The occasional VAR will slap their regular markup on top of the
-undiscounted- price, resulting in a quote that is more expensive than if you bought from Cisco directly with no discount!
