Note: If it is necessary to specify a value for Bridging, IP, and/or IPX, you must specify
all three of these values at the same time. You cannot specify just one or two of
them in the command line without the other(s).
Applying a Service Profile to an Active PPP Port
Once you have created one or more PPP service profiles, you can specify their use on one
or more active PPP ports on the SSR. The following command line displays a simplified
example of this process:
Configuring Multilink PPP Bundles
The Multilink PPP (MLP) standard defines a method for grouping multiple physical PPP
links into a logical pipe, called an “MLP bundle”. Large packets are fragmented and
transmitted over each physical link in an MLP bundle. At the destination, MLP
reassembles the packets and places them in their correct sequence.
The following table describes the commands for configuring MLP:
Compression on MLP Bundles or Links
Compression can be applied on either a bundle or link basis if MLP is enabled on PPP
links. If compression is enabled on a bundle, the packets will be compressed
before
