SSDP PROTOCOL (DLNA) NOT WORKING BETWEEN VLAN

Below is the solution to the problem. In any case, the discovery is not immediate (it takes a few seconds).

Here are the commands to execute on Putty

(L3-SW1)>enable
(L3-SW1)#configure
(L3-SW1)#ip multicast
(L3-SW1)#ip igmp
(L3-SW1)#ip pim dense

(L3-SW1)(config) #interface vlan 10
(L3-SW1)(interface vlan 10) #ip igmp
(L3-SW1)(interface vlan 10) #ip pim
(L3-SW1)(interface vlan 10) #exit

(L3-SW1)(config) #interface vlan 20
(L3-SW1)(interface vlan 20) #ip igmp
(L3-SW1)(interface vlan 20) #ip pim
(L3-SW1)(interface vlan 20) #end

With gui:

-Switching

                      -Multicast

                                             -Igmp Snooping  (ALL ENABLE)

                                             -Igmp Vlan Conf (Enable Vlan Ineresting)

                                             -Multicast Router Vlan (add Vlan and Enable)

                                             -Querier Configuration (Enable

                                             -Querier Vlan  Configuration (add ip Router VlanA+VlanB)

-Routing

                   -Multicast

                                            -Glabal Configuration (Enable)

                                            -Interface Configuration VLANS (VlanA+VlanB TTL2 "if necessary"

                                            -IGMP (Enable)             

                                            -Routing Interface (Enable VlanA+VlanB)

                                            -PIM Global Configuration  (Enable PIM-DM)

                                            -PIM  Interface Configuration VLANS (Enable VlanA+VlanB)

---------TO MODIFY PIM-DM IN THE FUTURE, YOU MUST FIRST DEACTIVATE PIM INTERFACE CONFIGURATION----------
