Cisco 2621XM routing metric issue

[LVDAX]

All right guys I am totally brain dead today.
I am in need of assistance with routing metrics. My friends company just
added a satellite internet fail over for internet service in case their
cable modem goes down. I need to keep this as simple as possible. I
can't run BGP or dial backup as neither the cable modem nor the sat
modem support these.

The setup is the cisco into a 5 port switch via FE 0/0
cable modem and sat modem into the same 5 port switch
This unfortunately can't be changed, it needs to stay this way for
now.
Serial0/0 into LAN gateway.
The soul purpose of this router is for internet fail over processing.


This is what my router currently looks like.
IOS 12.3
no network-clock-participate slot 1
no network-clock-participate wic 0
no aaa new-model
ip subnet-zero
ip cef
!
interface FastEthernet0/0
description $WAN$
ip address 69.181.50.122 255.255.255.248 secondary
ip address 69.169.235.226 255.255.255.248
speed 100
full-duplex
no cdp enable
no mop enabled
!
interface Serial0/0
description $LAN$
ip address 192.168.254.1 255.255.255.248

ip route 0.0.0.0 0.0.0.0 69.181.50.122 metric1
ip route 0.0.0.0 0.0.0.0 69.169.235.226 metric2

Im sure this looks totally wrong but if someone could give me a brief
example or a link to a web site to help kick start my brain i would be GREATLY appreciative.

Here is a diagram:

Thanks you in advance

Hmm, I know that you can configure 2 default routes but I don't know how well that works. Do the cable and the satellite modems support any routing protocol?


If that doesn't work you could try using route-maps and setting the next hop using access-lists to filter it.

 

[LVDAX]

unfortunately no...

Your static routing is not correct. You need to point your static route to the ip address of the far end interface.

ya i caught that after the post... I actually figured it out after sitting on it a while...
It looks like this for anyone who wants to know:
ip route 0.0.0.0 0.0.0.0 69.181.50.121 10
ip route 0.0.0.0 0.0.0.0 69.169.235.225 20

Thanks for you help guys...

Cute picture.

I haven't even started on my CCNA yet.. Can't help ya.

Thanks it was a quick GIMP throw together because i couldn't explain the setup without confusing myself. hahaha

It works great now but i swear my brain just wouldn't function that day...

BTW I have a copy of the 06 CCNA practice test if you want a copy... Just PM me and i'll stick it on an FTP site for you...

I'll have to hit you up on that at some time.. I'm trying to get into a MCSE 2k3 4 month course. Imagine that, they actually teach you instead of just getting you to memorize the answers for the exam.

Discounted price of $3500, down from $4500, whereas others charge $8-10k. Its all online too which is kind of nice since I travel a fair amount.

I am trying to find the other post but i couldn't find it thru the "great" search tool...
What is the training company you are using again?? I might want to go that route... The training guides i am using are pretty bland and monotone...

lvdax, you'd only need to set a value on the backup route, like this:

ip route 0.0.0.0 0.0.0.0 69.169.235.225
ip route 0.0.0.0 0.0.0.0 69.181.50.121 200

it will use the first route until that becumes unavailable. But do take not that the above only works if the modem in question is unreachable. If the modem has a static IP and it loses conection to the 'net the router will still pass traffic to the modem (unless the modem is smart enough to disbale the ethernet interface if the WAN link goes down - most are not).

I noticed you have /29 networks instead of /30, is that because of the ISP using another address in the same range? If so, you may want to use the IP address on the ISP side instead of the modem's IP.

Hey thanks for your help... I got it figured out, but appreciate your efforts...

Linux GIMP? If so, and you haven't already, try kiveo. Once you figure out how to install the computer/network stencils from sourceforge, you just drag and drop them and add the lines. Pretty sweet for free...
