2501 will not take RIP version 2

[comptek]

Hey guys,

I have 2 2501's to play with that are directly connected serials. I can ping the serials w/o problems. I can create static and default routes to the ethernet interfaces and can ping. My problem is trying to run RIP. My setup is 192.168.5.8 /30 for my directly connected serial interfaces, and the ethernets are 10.10.64.0/24 and 10.10.65.0/24. When I try to run rip for the 10.10's they do not show up when in the route tables. I thought it may have to do with the fact that of VLSM so I ran the version 2 command. One router took the command and i can see it when I run a sho run command. The other router lets me run the command but when I do a sho run "version 2" is not listed. When I go back to run the version 2 command again I will get into router config mode type in "vers?" to get the router to help me with the command and the router say's "command not recognized". What could be the problem with my setup do I need to run Ver2?
The only other routing protocol that I can use is EIGRP. I tried OSPF and it did not work. I am going to be taking the ICND pretty soon here. Should I even be worried about RIP at this point or should I just move on? I thought the reason why "version 2" would not work is because of the IOS on the router so I upgraded it to the sameone the other router (that displays "version 2") has and it still does not accept version 2. I did not send the configs because I am not at the routers at the moment. I will be home in the afternoon, but if anyone has any suggestions I am willing to listen.

Thanks

Hi,
Looks like a IOS verion problem to me. Show us your show version. Not quite sure which IOS version started to support RIP version 2! Anyone?

I will send it later on tonight when I get home. The router had I believe version 10. The other router that would accept the rip version 2 command had IOS version 11. So what I did was a copy flash tftp of router 2 (the one that accepted it) and I used that copy to flash router 1. The wierd thing that I noticed and am not sure if it is normal (at least not the same in my sybex book as far as flashing IOS) was that when I went do copy tftp flash to router 1 it listed that 2 partitions (1 and 2 ) with 2 as the default to wipe out and install on. I noticed that partition 1 was read only also. Needless to say the flashing of IOS worked . It said completed, but I will check and send it hear for sure. I guess the good part is that I know how to flash my routers IOS and I have not even gotten to that chapter yet.

Thanks for your help.

Here is the result of sh run. I am enclosing both. Keep in mind that the one that accepted the version 2 message is router2, router1 will not.

comptek,

Yep, that is your problem the IOS release, RIP version 2 is available from IOS 11.x. Let us know if you managed to get RIP 2 available on the box you upgraded.

Hope it helps.

Absolutely IOS version issue, which is why the command is not supported. Check your flash and see how much space you have, but you should be able to run 12.1 or 12.2 with no problems and have support for this.

Thanks guys.

I tried to flash the IOS to version 12 but I did not have enough space on my router. How big is the version 12 IOS typically? Router1 has been partitioned out to 2 partitions. Partition 1 is R/O and has 4943440 bytes used, 3445168 bytes available, 8388608 bytes available.
Partition 2 is in R/W and has 3627940 bytes used, 4760668 bytes avail, 8388608 bytes total. Everytime I flash it will only go to partition 2. Partition 2 is not big enough to hold the version 12 IOS that I got from ciscokits when I bought the router last year. When I try to do an erase flash, it defaults to partition 2 only. When I type in '1' to try and select partition 1 it cancels my request.

Is partition 1 needed? I dont know what it is for. Router 2 is not partitioned out. So I was thinking maybe if there was away to erase partition 1 and 2 and make it a "Whole" that may help.

What do you guys think?

Just wanted to let you know guys that flashing it to 12.3 allows me to now use rip version 2. I had to delete the 2 partitions and then load 12.3. After reloading though it took an extreme amount of time about 10-minutes. Then finally a sceen came up with the following message "%Error: Erasure of partition 1 required." Then w/o doing anything "Press Return" come up. When I do that it goes through the whole initialzation process (checking interfaces etc.). Another message pops up " %SNMP-5-COLDSTART: SNMP agent on host Router is undergoing a cold start. If I hit enter it brings me to a router prompt and all of me settings are in tact.

Should I be worried at all about those messages? Oh and by the way have when you took the ccna how much of RIP v1, or v2 was emphasized on your exam? Just wondering because although I can do more now with this router hopefully I just wanted to know if spending this much time to get RIP to work was worth it for the ccna especially when EIGRP and OSPF are available.

Thanks again

comptek,

In my opinion RIP v1 and RIP v2 will be the least of your worries on the CCNA. You will have lots more to understand with OSPF and EIGRP.

As far as RIP - have seen a sim where you had to setup routing with RIP (Also one with setting up OSPF) understand that it is a distance vector routing protocal, understand it sends updates every 30 seconds by default, has a limit of 16 hops, uses hop count as the metric and I think the only real difference between v1 and v2 is that v1 sends updates by broadcast 255.255.255.255 and v2 sends them by multicast 224.0.0.9.

There are a few other differences and they are covered in detail at the link below.

Very good RIP comparison here -

Thanks for your response. Yeah I figured but just wanted to make sure. Either way if you have read the whole thread I went from trying to figure out why rip v2 would not work on one router (the command anyway) but would on another to wiping out the flash and partitions to loading a new IOS. Not bad I think since I have not gotten to that chapter in the book. If what I went through was in the ICND exam, I have the confidence to know that I can do the IOS upgrade.

Thank you also Drae73 and Niltinho for your help getting and info. It was a real help.
