IOS VERSION FOR MPLS

Hi! i'm trying to do a lab at my university implementing MPLS. I have routers cisco 2610 series. This is my configuration:

Cisco2600-2(config-if)# ip route-cache cef

Cisco2600-2(config-if)# mpls label protocol ldp

Cisco2600-2(config-if)#mpls ip

My problem is that i can't use te "set mpls experimental topmost " command at the policy-map. My options are:

Cisco2600-2(config-pmap-c)#?

QoS policy-map class configuration commands:

bandwidth Bandwidth

compression Activate Compression

drop Drop all packets

exit Exit from QoS class action configuration mode

no Negate or set default values of a command

police Police

priority Strict Scheduling Priority for this Class

queue-limit Queue Max Threshold for Tail Drop

random-detect Enable Random Early Detection as drop policy

service-policy Configure QoS Service Policy

shape Traffic Shaping

My version of the IOS is:

IOS (tm) C2600 Software (C2600-TELCO-M), Version 12.3(15b), RELEASE SOFTWARE (fc1)

wich version do i need to run this command and configurations?? Any information will help. Thank you very much. Best regards!!

Re: IOS VERSION FOR MPLS

It is my understanding that you don't have that capability in those images (or platform). I didn't find the feature in the feature set of the 2600 platform. The feature you are looking for is: "MPLS Quality of Service (QoS) Enhancements"

From the feature set definition:

- MPLS quality of service enhancements allow service providers to classify packets according to their type, input interface, and other factors by setting (marking) each packet within the MPLS experimental field without changing the IP precedence/DSCP field. For example, service providers can classify packets with or without considering the rate of the packets that PE1 receives. If the rate is a consideration, the service provider marks in-rate packets differently from out-of-rate packets.

Re: IOS VERSION FOR MPLS

Javier/William, 'set mpls experimental topmost/imposition' is there since 12.2T.

The current IOS which is being used doesnt have the feature "class based marking" hence no set commands are there.

Javier try downloading a enterprise plus or basic sw for your router to mark EXP bits into the labels.

Although do check your available memory as it would need minimum 64MB.(EntBasic)

HTH-Cheers,
