Hi Cisco community,
I was wondering if there is a known problem as to why the ip multicast-routing [distributed] option is not available on the Cat 3850 platforms
global command " ip multicast-routing " is accepted
the configuration guide named:
IP Multicast Routing Configuration Guide, Cisco IOS XE Release 3SE (Catalyst 3850 Switches)
First Published: January 29, 2013
Last Modified: October 22, 2013
explains that this option "key word" [distributed] should be available>
Enables IP multicast routing.
ip multicast-routing [distributed]
Device(config)# ip multicast-routing distributed
=============== Here is what i have and see =========
Config attempt
============
CAT-3850-1(config)#ip multicast-routing distributed

Any hints and help would be greately appreciated.
Many thanks in advance

Hi,
This could be a typo in the config guide as there is no "[distributed]" option is available in the below config guide:

Hi Markus,
Thanks for the rating.
The "distributed" keyword is used in different Cisco switch platforms i.e 6500, 7600, 12000, etc..
and no in smaller platform i.e 3560, 3850, etc...
Please have a look at this document for more info

Hi Reza,
Thank you for your quick reply, and for putting the record staright. As such, a helpful rating was provided
PS: Feel free to help me one more time if you happend to know folllow on this query :)>
I guess that the disributed function has been included in the standard mulitcast routing command because the key word is no longer needed. Or perhaps this platform does not support this at all.#
Once again , thank you for your help above.
Best regards

Hello Reza,
Don’t mention it:)
Of course, now it makes sense. Similar to CEF etc...which is downloaded on line cards.
So yes, this function is not needed/used on fixed chassis switches.
Thanks for the info / link and help,
PS: another useful rating.
This post and question has been successfully and indeed satisfactory resolved.
Best regards and until next time.
