in Figure 10 on page 230). The connection joins the interface that comes from the
circuit s source to the interface that leads to the circuit s destination. When you
specify the interface names, include the logical portion of the name, which
corresponds to the logical unit number. The cross-connect is bidirectional, so packets
received on the first interface are transmitted out the second interface, and those
received on the second interface are transmitted out the first interface.
Configuring MPLS for Switching Cross-Connects
For Layer 2 switching cross-connects to work, you must configure MPLS. The following
is a minimal MPLS configuration:
For more information, see the JUNOS MPLS Applications Configuration Guide.
Configuring IS-IS or MPLS Traffic for TCC Interfaces
Layer 2.5 VPNs on T Series, M120, MX Series, and M320 routers support IPv4, IS-IS,
and MPLS traffic types. By default, IPv4 traffic runs on T Series, M120, MX Series,
and M320 routers and over TCC interfaces. To configure IS-IS (ISO traffic) or MPLS
traffic on Layer 2.5 VPNs, you must configure the same traffic type on both ends of
the Layer 2.5 VPN.
To specify which traffic can run over a TCC interface, include the
with the appropriate value (
unit logical-unit-number family tcc]
NOTE: Layer 2.5 VPNs running on M Series Multiservice Edge Routers support only
IPv4 traffic. IPv6 is not supported on Layer 2.5 VPNs.
When enabling ISO over a Layer 2.5 VPN that is configured on a CE Ethernet interface,
you must also include the
