2620XM try

12.2.15T17 Enterprise Basic

c2600-j1s3-mz.122-15.T17.bin

or

12.3.18 Enterprise Basic

c2600-j1s3-mz.123-18.bin

or

12.3.18 Telco Feature

c2600-telco-mz.123-18.bin

Regarding the 2600XM, is MPLS supported going forward? It looks like it disappears in 12.4 code.

Best Regards,

On versions upper than 12.25 tag swicthing changes to : mpls label protocol ldp

You can activate MPLs whit de next configuration:

ip cef distributed

mpls ip

mpls label protocol ldp

over OSPF or IS-IS

[Harold Ritter]

Unless there is a requirement for MPLS TE, you can configure MPLS over any IGP (or static) not just ISIS or OSPF.

Hope this helps,

1: You can check flash and memory of your router (you can get this information with "show version")

2: Any SP (service provider) version upper than 12.3 works with MPLS.

I think that you can work with :

c2600-spservicesk9-mz.123-3i.bin with: flash (MB):32 Mem (MB):96

c2600-spservicesk9-mz.123-18.bin with: flash (MB):32 Mem (MB):96

c2600-spservicesk9-mz.124-1c.bin with: flash (MB):32 Mem (MB):128

c2600-spservicesk9-mz.124-7a.bin with: flash (MB):32 Mem (MB):128

It looks like MPLS really does disappear in 12.4 code for the 2651XM (see below). It's too bad because I could use the features and would rather not have to replace a bunch of routers.
