For basic Multicast Routing:

We will create two vlans, VLAN 7 (for subnet 172.17.10.0/26) for input traffic, and VLAN 9 (for subnet 172.10.12.0/26) for output traffic.

$ configure terminal
#(c) vlan 7
#(c) name input_mca
#(c) interface vlan 7
#(c-int) ip address 172.17.10.1 255.255.255.192
#(c-int) no shutdown
#(c-int) ip pim sparse-mode ; sparse mode needs for a RP, see line 17
#(c-int) exit
#(c) vlan 9
#(c) name ouput_mca
#(c) interface vlan 9
#(c-int) ip address 172.17.12.1 255.255.255.192
#(c-int) no shutdown
#(c-int) ip pim sparse-mode ; sparse mode needs for a RP, see line 21
#(c-int) exit
#(c) ip pim rp-address 172.17.10.1 ; input interface vlan ip address
#(c) ip mutlicast-routing
#(c) interface vlan 9
#(c-int) ip igmp join-group 232.0.0.1

This will make that the multicast route is being sent to the vlan, to check this, use:

$show ip igmp groups
$show ip mroute

For advanced IGMPv3 Multicast Routing:

We will create two vlans, VLAN 7 (for subnet 172.17.10.0/26) for input traffic, and VLAN 9 (for subnet 172.10.12.0/26) for output traffic.

$ configure terminal
#(c) vlan 7
#(c) name input_mca
#(c) interface vlan 7
#(c-int) ip address 172.17.10.1 255.255.255.192
#(c-int) no shutdown
#(c-int) ip pim sparse-mode ; sparse mode needs for a RP, see line 17
#(c-int) ip igmp version 3
#(c-int) exit
#(c) vlan 9
#(c) name ouput_mca
#(c) interface vlan 9
#(c-int) ip address 172.17.12.1 255.255.255.192
#(c-int) no shutdown
#(c-int) ip pim sparse-mode ; sparse mode needs for a RP, see line 21
#(c-int) ip igmp version 3
#(c-int) exit
#(c) ip pim rp-address 172.17.10.1 ; input interface vlan ip address
#(c) ip mutlicast-routing

Now, open your recevier device and request a join for that multicast. What this will do is that will send the reques through the VLAN 9 to the router, and then the router will look for the multicasts and forward them if there are no filters/access lists applied. To check this, use:

$show ip igmp groups detail
$show ip mroute
