Table 57: Encapsulation Inside Circuits Ccc-Connected By Vlan-Bundled - Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual

Table 57 on page 633 describes the logical link-layer encapsulation types used within
circuits connected using VLAN-bundled logical interfaces of the same type.

Usage
Guidelines
The MX Series router automatically uses
For a Single-Tag
as the Layer 2 protocol used to encapsulate
Logical Interface
incoming traffic. Although the connection spans
multiple VLANs, the VLANs are bundled and
therefore can be encapsulated as a single VLAN.
NOTE: With
signal processing does not check that the VLAN
ID list is the same at both ends of the CCC
connection.
Configure the MX Series router to use
For a Dual-Tag
Logical Interface as the Layer 2 protocol to encapsulate incoming
traffic.
With
ethernet-vlan
processing checks that the VLAN ID list is the
same at both ends of the CCC connection. If a
VLAN ID list mismatch is detected, you can view
the error condition in the
command output.
