Overview

You can create bridged IP interfaces on an E-series router to manage IP packets that are encapsulated inside an Ethernet frame running over a permanent virtual circuit (PVC).

Bridged IP interfaces can be configured on an ATM subinterface. You can create one occurrence each of the following on a bridged IP interface:

• PPPoE interface
• CBF interface
• IP address

Stacking containing more than one interface type is also known as hybrid PVC. (See Figure 13.)

Figure 13: Structure of Bridged IP Interface

After a PPPoE interface, CBF Interface, or IP address is created on a bridged IP interface, its menu choice is removed from the Create pop-up menu because only one of each interface type is allowed per bridged IP interface. Therefore, if a choice does not appear in the pop-up menu, that interface has already been created on the selected bridged IP interface.

You can also establish a CBF connection between two bridged IP interfaces by using the NMC-RX application.
