Guidelines for Configuring Logical Tunnels on ACX Series Routers

Copyright © 2017, Juniper Networks, Inc.
When configuring logical tunnel interfaces, note the following:
You can configure each logical tunnel interface with one of the following encapsulation
types: Ethernet, Ethernet circuit cross-connect (CCC), Ethernet VPLS, Frame Relay,
Frame Relay CCC, VLAN, VLAN CCC, or VLAN VPLS.
You can configure the IP, IPv6, International Organization for Standardization (ISO),
or MPLS protocol family.
Do not reconfigure a logical tunnel interface that is an anchor point with pseudowire
devices stacked above it unless you first deactivate all broadband subscribers that are
using the pseudowire subscriber interface.
The peering logical interfaces must belong to the same logical tunnel interface derived
from the Tunnel Services PIC or Adaptive Services Module.
You can configure only one peer unit for each logical interface. For example, unit 0
cannot peer with both unit 1 and unit 2.
To enable the logical tunnel interface, you must configure at least one physical interface
statement.
Logical tunnels are not supported with Adaptive Services, Multiservices, or Link Services
PICs (but they are supported on the Adaptive Services Module on M7i routers, as noted
above).
On M Series routers other than the M40e router, logical tunnel interfaces require an
Enhanced Flexible PIC Concentrator (FPC).
On MX Series routers, logical tunnel interfaces require Trio MPC/MIC modules. They
do not require a Tunnel Services PIC in the same system.
For more information about configuring logical systems, see the Junos OS Routing
Protocols Library.
Tunnel Services Overview
Example: Configuring Logical Tunnels
Observe the following guidelines while configuring logical tunnel (
Series routers:
You can use a logical tunnel interface to connect only bridge domains and pseudowires.
Logical tunnel interfaces cannot interconnect the following links:
Pesudowire and a routing instance (Pseudowire terminating on a VRF)
Two routing instances
VPLS instance and a routing instance
Two VPLS instances
