Enabling Bridging on an Interface
When bridging is enabled for an interface, PPP accepts bridged traffic in the
specified encapsulation and forwards it over the PPP network. Site Manager lets
you enable or disable bridging for Ethernet, FDDI, and/or token ring encapsulated
packets. By default, all these parameters are enabled. If you change any of these
parameters dynamically (that is, for a router that has already completed its
negotiations), you must force LCP renegotiation on the interface, as previously
described.
Before you can enable a particular type of encapsulated bridged traffic, you must
enable bridging on the interface. You do this by default if you enabled bridging
when you initially set up the PPP interface, but you can disable or re-enable it
here. To stop traffic from being bridged over this interface, set this parameter to
Disable.
The Bridge Enable parameter enables or disables the network control protocol for
the bridge. It does not enable or disable bridging services for the interface.
However, disabling the network control protocol for the bridge stops traffic from
being bridged over this interface.
With the bridging feature enabled, you can then enable or disable bridging for
particular encapsulation types. For example, if you want PPP to accept and
forward Ethernet-encapsulated bridged traffic, set the Bridge Ethernet parameter
to Enable (the default).
