Issue with IPv6 EIGRP on Cisco 3750X Switches

[samialrustom]

Hi everyone,

I'm using Cisco 3750X series switches in my home lab for practice, but I'm encountering an issue when configuring IPv6 with EIGRP. When I try to enable IPv6 EIGRP, I receive the error: "Failed to create routing protocol eigrp", even though IPv6 unicast routing is enabled.

This issue occurs on all three of my switches, all of which are the same model. Is there a way to resolve this?

Thanks in advance!

Hello,

What commands are you using?

From the document below it looks like you may only need to enable it on the interface.

The Cisco 3750X series comes with different IOS feature sets, such as IP Base and IP Services.
IPv6 EIGRP requires the IP Services feature set; it is not supported in IP Base.
You can check it  #show version | include IOS

Thanks !

S1#show version | include IOS
Cisco IOS Software, C3750E Software (C3750E-IPBASEK9-M), Version 12.2(55)SE7, RELEASE SOFTWARE (fc1)

[samialrustom]

how can I switch to IP Services?

[Joshqun Ismayilov · Accepted solution]

You need to change the IOS version

Thanks!

Are you using SDM templates that support IPv6 routing?

But, for that particular error, the issue is likely due to IOS version being used, as already described by @Joshqun Ismayilov .

[samialrustom]

Oh ok, well, I guess I can't do much about it because I don't have a different IOS to update the switches to.

[samialrustom]

Thank you all for your help with issues, since the 3750X can't support EIGRP because of IOS version I decided to upgrade to 3850 which is doing great for EIGRP and OSPF Lab testing.

For the benefit of other readers, lack of EIGRP (or OSPF), wasn't, I suspect, ". . . because of IOS version . . ." but due to not having the necessary feature set, i.e. IP Services rather than IP Base.

On the older platforms, feature sets were actually provided by different IOS files.  (Legally, you needed a corresponding license to run additional features, but there was no license enforcement on the device.)

On current platforms, the IOS file is a "universal" image that contains all the possible features (except perhaps advanced crypto), and the advanced features are license locked.  I.e. you need an additional license to unlock the additional feature(s).

I recall (?) the 3850/3650 series was one the the first to adopt the new universal file images with additional feature license unlocks.  Often, these new IOS versions support a temporary unlock, so you can try out advanced features or while waiting for the actual feature license to be received.
