Use the no version to disable MLPPP on an interface.
See encapsulation mlppp.
Use to create an MLPPP network interface, also known as the MLPPP bundle.
Example
host1(config-if)#interface mlppp group2
Use the no version to delete the MLPPP bundle. You must first delete the IP interface,
followed by deleting the bundle members (link interfaces); then you can delete the
MLPPP bundle.
NOTE: RADIUS supports the inclusion of the MLPPP Bundle Name VSA [26-62] in
Access-Request, Acct-Start, Acct-Stop, and Interim-Acct messages. For more
information, see JunosE Broadband Access Configuration Guide.
See interface mlppp.
Use to add an MLPPP link interface—also known as an MLPPP bundle member—to an
MLPPP bundle.
Example
host1(config-if)#member-interface serial 2/0:1/1
Use the no version to remove the specified interface from the MLPPP bundle.
See member interface.
Use to enable use of a hash-based algorithm to select the link on which the router
transmits non-best-effort (high-priority) packets, such as voice or video, on an MLPPP
interface.
Hash-based MLPPP link selection is available only for non-best-effort traffic. For
best-effort traffic, the router uses a round-robin algorithm for link selection.
Using hash-based link selection instead of the default round-robin link selection for
non-best-effort traffic ensures that the router maintains the proper packet order when
transmitting high-priority packets.
When you configure hash-based link selection, the router uses the IP source address
and IP destination address of the packet as a hash to select the MLPPP member link
on which to transmit the packet.
You can configure hash-based MLPPP link selection in any of the following ways:
To configure hash-based link selection for an individual MLPPP member link interface,
issue the ppp hash-link-selection command from Interface Configuration mode or
