Outgoing multilink options
The following options define how a bundle will handle outgoing
multilink PPP connections:
Minimum number of active links-
The minimum number of links that can remain in a bundle when bandwidth on
demand has removed excess capacity.
The value entered must be less than or equal to the
number of links configured for the bundle.
Maximum number of active links-
The maximum number of links that can be active in a multilink
bundle. A number greater than 1 indicates the
use of a multilink bundle.
The value entered must be less than or equal to the
number of links configured for the bundle.
Maximum received reconstructed unit size-
The size of the maximum received reconstructed unit
(MRRU) which is the maximum size in bytes of the
information fields of reassembled packets.
This must be defined if multilink connections are required.
NOTE:
It is suggested that the value configured for the
MRRU should be at least 6 bytes smaller than the
maximum receive unit (MRU) that is set in the
Link Control Protocol
for the member links of the bundle.
Use short sequence numbers-
Whether short sequence numbering is enabled.
If enabled, PPP informs the peer that it wants
to receive fragments with short, 12-bit sequence numbers rather than
24-bit sequence numbers.
Use endpoint discrimination-
Whether endpoint discrimination is enabled.
A system's endpoint discriminator identifies it to its peer
when it tries to create a new multilink bundle or to add
a link to an existing multilink bundle.
Packet size at which fragmentation stops-
The minimum fragmentation size in bytes for a link.
Packets with a size less
than this will not be fragmented before being sent.
Maximum number of pending fragments-
The maximum number of fragments that may be queued for reassembly
per active (open to traffic) link in a bundle.
Inhibit control packet encapsulation-
Whether Control Protocol packets are
encapsulated within the multilink header.
Set this to Yes for a multilink bundle
to allow PPP in UnixWare® 7 to interoperate with
other PPP implementations that cannot
interpret encapsulated Control Protocol packets.
NOTE:
The preferred
MRRU, short sequence numbering and endpoint discrimination
characteristics of incoming connections must be set in the
global bundle.
These values are applied to all incoming connections
because PPP must negotiate the multilink
characteristics of the connection before it can associate the caller
with a bundle.
WARNING:
You should normally adjust only the maximum and minimum number of links
to be used in a multilink bundle. Only change the other settings
if you fully understand multilink PPP, or if
the site at the remote side of the link provides you with values
that are more suitable for the implementation of multilink
PPP that they are using.
Refer to RFC 1990 for more information about multilink PPP.
