Route redistribution with rip and igrp

topstar

Hi
Im practicing setting up rip and igrp at the minute. I have 4 routers and would like some information on setting up rip or igrp with static routes with redistribution as a back up line.
I want to set up the 4 routers with igrp or rip and have extra cables so I would like to have a backup line encase my main line goes down (actually for when I sabotage it)
I would like to have this backup line as a static route and to be advertised by rip when the main line goes down (redistribution static?)
Could someone please explain to me exactly how I would go about this please be as specific as possible with the commands i would need on the two routers with the backup line.
Also I have done this before but just with the static route command and just give it a higher Ad than rip but not with the redistribute command and although it worked the line was always up (but not in the routing table until the main line went down ) is there any way to do this and keep the line down until it is needed then it could bring itself up. It will just be a normal serial line.

Thanks
Stephen

r1
interface $INTERFACE
bandwidth 128 128
ip address 10.10.10.1 255.255.255.0
standby 10 ip 10.10.10.254 10.10.10.254

r2
interface $INTERFACE
bandwidth 1500 1500
ip address 10.10.10.2 255.255.255.0
standby 10 priority 150 150 preempt delay 10 10
standby 10 ip 10.10.10.254 10.10.10.254
standby 10 track serial 0 60

and so on and so forth. You could always throw some security in the loop and use crypto maps then try out reverse-route More than likely though, stick with a variation of above

Hi sexion8
Thanks for the help but could you please explain what some of it means, as it is I could do it ok but I would not have a clue what I really doing or why. Im not trying to sound ungrateful but I like to know what im doing and why I doing it a certain way. Like why is the bandwidth different on the two routers when it’s the same link? And I take it configuring it like this the line stays down until it’s needed? Also would this be redistributed by rip or igrp?
As I said before thanks for taking the time to respond but could you please be a bit more specific.

Thanks

I looks like you had done a floating static route....

HSRP (or VRRP) lets 2 routers share and route a single IP (and MAC), but the "unused" interface is up.

Check out the backup interface command on the Cisco site. The backup interface is placed in stand by mode.

Definitely don't mean this in any way other than a helpful one. You should invest in some books and perhaps some time on Cisco's website in order to find out how the IOS works in situations. Judging from your response, you seem to lack a lot of knowledge for what you intend on doing. I don't mean this to sound rude at all, I mean this in a sincere way.

I buy and have bought 95% of my books from there. I have well over 30 Cisco books. The average price I spend is about $7.00 per book, $3.00 shipping. Well worth the investment if you intend on obtaining your certifications. Figure it like this... Cup of coffee @ .30 a day (which is insanely low) for a month comes out to an average price of a book.

Its nice to have equipment and say "I want to do this with x amount of equipment". When you don't know how to operate it properly its advisable you begin from the ground up.

Hi
No offence taken but I do have a good grasp of what im doing and how to set up the basics (im only in semester 2 of the networking academy at the minute and still have a lit to learn). And am currently working from the companion guide and the sybex books but they do not cover this and the Cisco book is very vague in its description of redistribution (this may become clear in semester 3 or 4).
The way I work is I have to fully understand what im doing and why im doing it, and what it means as I said before thanks for the help and don’t worry no offence taken.
You’re probably right in saying I need more books, I going to try to find a good lab book to supplement what im learning.

Thanks mike for pointing out the Cisco site I found what I needed there.
