Configuring Md Vpn - HP FlexNetwork 7500 Series Configuration Manual

•
The PIM mode on the MTI must be the same as the PIM mode running on the VPN instance to
which the MTI belongs. When at least one interface on the VPN instance is enabled with PIM,
the MTI is enabled with PIM accordingly. When all interfaces on the VPN instance are
PIM-disabled, PIM is also disabled on the MTI.
