Hello, we have a new cisco 2811 with wic-t1-csudsu-v2 card and are trying to configure it for a t1 frame relay line from uunet/mci/verizon. The line has been in place and up & running with an old "router" for sometime(~6yrs), but the old router is starting to have issues so we are replacing it. I just started working here and they want me to get the new cisco setup and ready to replace the old unit.
The problem is the person who originally setup this old livingston/pm3 "router" is no longer working here and they cant seem to find the original config info from verizon. We called verizon and got a "ticket number" a day ago, but no info yet from them. I have setup several types of more basic routers and am just starting with some cisco classes, but I am really a cisco newb. The cisco is amazing in all the options it has, but can be a bit overwhelming for a cisco newbie.
I have read through quite a bit of cisco docs and whatnot, and searched through the forum and I think I have "converted" the setup info from the old router into the 2811 correctly. I have been able to get several bits of info out of the old router, but it is pretty old and some of the terminology seems abit different, so I was hoping someone could glance over my cisco config and tell me if im even close to converting it correctly!
Basically we have a DS1/T1 frame relay line from "verizon", and we are allocated a full class c /24 block of ip addresses. I have attached the info from the old router and the running config from the 2811.
For a point to point connection like your Frame Relay link a static route works about the same whether it specifies the next hop address (as you used to do) or whether it just specifies the outbound interface. That is not true for multi access interfaces (especially for Ethernet) and for these it is much better to use static routes that specify next hop addresses. My advice is that if there is already a static default route specifying next hop then I would not bother to change it.
"subnet-zero" and "ip classless" are interesting exceptions to the rule that default values do not show up in the running config. Both of these are default values that do show up in running config (or have for quite a while, but I believe that in very recent 12.4T are no longer showing up). The reason that they have been showing up in the running config is that the default behavior changed. If you go far enough back the default was no subnet-zero and no ip classless. Then as network environments changed Cisco changed the default behavior and they have made these commands show up in running config to make it more obvious what the behavior is.
I would not worry about these commands being in the config and I absolutely disagree with the advice from Nikhil that you could remove the ip classless command. You do NOT want to remove that command from your config. I suggest that you just leave them alone - and also the multilink bundle-name authenticated can just be left alone.
If the Verizon tech says that they do not need RIP then I would certainly remove it from the config.
