mask — The mask associated with the IP prefix expressed as a mask length or in dotted decimal
notation; for example /16 for a sixteen-bit mask. The mask can also be entered in dotted decmial
notation (255.255.0.0).
Values 4 — 32
netmask — The subnet mask in dotted decimal notation.
Values 0.0.0.0 — 255.255.255.255 (network bits all 1 and host bits all 0)
mdt-threshold — Specifies the threshold, in kilo-bits per second (kbps), for the group to which this C-
(S,G) belongs. For a C-group G configured with a threshold, a C-(S,G) is mapped to a Data
Multicast Tunnel (MT) only if the C-(S,G)'s rate exceeds this configured threshold.
default
Syntax default grp-ip-address
no default
Context config>service>vprn>pim>mdt
Description This command configures a default multicast distribution tree (MDT) group address used by the core
instance of PIM to identify multicast traffic for this VPRN instance. All PE’s that are configured with
the same MDT address will become members of this group and receive multicast traffic from each
other.
The no form of this command removes the MDT default address from the configuration.
Parameters grp-ip-address — The multicast IP address for the group.
Values 224.0.1.0 — 239.255.255.255
join-tlv-packing-disable
Syntax [no] join-tlv-packing-disable
Context config>service>vprn>pim>mdt
Description This command specifies enables the packing of MDT join TLVs. If multiple Join TLVs are available
at the time they are transmitted. The TLVs are packed into a single UDP PDU instead of sending
separate UDP PDUs. In scaling scenarios, this packing makes more efficient use of packet buffers
and helps with better convergence.
non-dr-attract-traffic
Syntax [no] non-dr-attract-traffic
Context config>service>vprn>pim
Description This command specifies whether the router should ignore the designated router state and attract traffic
even when it is not the designater router.
