Real example:
2 data centers connected with VLANs, both with Cisco ASR-9K on L3.
Routers have its own vni-multicast group mappings.
Router(config-if)# member vni 6010-6030 multicast-group 225.1.1.1
So we can create network with vni i.e. 6011 and it will get right multicast address.
We also need to create networks on demand and not configure routers at each change.
