router rip command on Cisco IOS 11.x

javedakbar · April 2010

Guys, I am trying to run router rip on my cisco 2500 router which is running IOS 11.x, but it doesn't recognize it for some reason.

from enable mode:

conf t
router-config # router rip

It has worked on my other two routers in the network which are both running 12.x, but the one running 11.x doesn't like it.

Thanks in advance.

RIP did exist back in the 11.x days, but so did a lot of other protocols. What Feature Set are you running (show version)? You might have a Novell IPX feature set or a funky IBM protocol feature set.

You didn't show us any terminal output -- so are you sure you're in config mode?
What does router ? show you (assuming you are in config mode)?

router rip was added in 10.0.

My 2501 is running 11.0(5) and my 2507 is running 11.2(17).

I checked both routers and the rip command works.

CFN only goes back to 12.0 and RIP is in IP base there. No idea what it would be for 11.x though.

I would love to see an 11.x (or older) IOS. It would be pretty cool to see the evolution of the IOS from that early on to what we know it as today. Didn't check google prior to this post... but at what version did the IOS begin? Was it IOS version 1 or did it skip around (like it did from 12.4 to 15.0)?

I found version 10.0 info, but nothing on 9.0? and earlier...maybe 10.0 was the beginning? If so, why did they choose 10?

The Cisco IOS® Software 10.x releases were introduced in 1993 and have all reached end of sale (EOS) and end of life (EOL). Cisco IOS Software Release 10.0, also known as the A train, provided very important internetworking capabilities to the routers. Advanced routing features such as Hot Standby Router Protocol (HSRP), Border Gateway Protocol version 4 (BGP4), NetWare Link Services Protocol (NLSP), E1 Primary Rate Interface (PRI) signaling, Point-to-Point Protocol (PPP) compression, new dial-on-demand routing (DDR) protocols, fast call rerouting, and Link Access Procedure, Balanced (LAPB) were introduced with this release.

Cisco IOS Software Release 10.2(1) first customer shipped (FCS) on October 4, 1994, and delivered maintenance releases through 10.2(15). It reached end of engineering (EOE) on December 30, 1996.

Cisco IOS Software Release10.2(9) was the first Cisco IOS to achieve general deployment (GD) status.

Cisco IOS Software Release 10.3(1) was released on April 13, 1995, and delivered maintenance releases through 10.3(19).
