multicast on vrf on 4506 switches

Hi experts 

we have   a  4600  series  switch and  i am  trying to configure  multicast  inside  a vrf .

  core(config)#ip multicast-routing ? 

as  i see we dont  have  support  for   vrf  multicast   right now .

ie   ip multicast-routing vrf  VPNA    command is not available   

CORE#show ver Cisco Internetwork Operating System Software IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-I5S-M),

Version 12.2(20)EWA4, RELEASE SOFTWARE (fc2) Technical Support:

System image file is "bootflash:cat4000-i5s-mz.122-20.EWA4.bin  ..

is the support  for  multicast  inside   a  vrf  available  for  4506 ?  if  yes  what version  should  i upgrade to  ??


Gents    i am trying to  find  ip multicast-routing vrf  support  in  command  reference  of  4500 series  images , but  unable to find one

This feature does not seem to be supported on 4500. I could not find it for 4500 in feature navigator and not in the configuration guide either. I saw that it was supported for 3750, 6500, 7600 and so on.

Hello people,

On the version that you are running at this moment, version 12.2(20)EWA4, multicast routing VRF is not supported, however, looking on the configuration guide for the 4500 I found the command enable after the version 12.2(50)SG:

(Log in is needed):

Switch(config-vrf)# ip multicast-routing vrf

(Optional) Enables global multicast routing for VRF table.

Check if the version 12.2(50)SG is compatible with the supervisor engine that you have on the 4506 prior to upgrade to the IOS version

Hi Ehtesham,

You need supervisor 6-E for this to work.
