Specifying the default-group
Restrictions and guidelines
You must specify the same default-group on all PEs that belong to the same MVPN.
The default-group for an MVPN must be different from the default-group and the data-group used by any other MVPN.
For an MVPN that transmits both IPv4 and IPv6 multicast packets, you must specify the same default-group in MVPN IPv4 address family view and IPv6 address family view.
