Dear colleagues,

I have a doubt regarding the MDT routes in ME3600 platforms. The template shows 
the following information:

Switch#sh sdm prefer current
The current License is AdvancedMetroIPAccess
The current template is "applications" template.

Template values:
      number of mac table entries                        =  16000
      number of ipv4 routes                              =  12000
      number of ipv6 routes                              =  4000
      number of routing groups                           =  1000
      number of multicast groups                         =  1000
      number of bridge domains                           =  4096
      number of acl entries                              =  2000
      number of MDT mroutes                              =  250
      number of ipv6 acl entries                         =  1000
      number of ipv4 pbr entries                         =  2000

The maximum MDT routes is 250. I understand that the devices will not learn 
more than 250 routes and then the GRE tunnels that are created to encapsulate 
the multicast traffic will not be created anymore. Do you know if there are 
some commands to tune the TCAM partition? Do you know if in MPLS environment it 
is possible to build the multicast tunnels as hub & spoke instead of full-mesh?
