Configuring VPLS Interaction With Other Features
OmniSwitch AOS Release 6 Network Configuration Guide September 2009 page 11-11
Interaction With Other Features
This section contains important information about MPLS-based VPLS interaction with other OmniSwitch
features and interoperability with the Alcatel-Lucent SR Series. Refer to the specific chapter for each
feature to get more detailed information about how to configure and use the feature.
Access (Customer-Facing) Ports
Switch ports and link aggregates are configured as VPLS service access ports to handle customer traffic
ingressing on the provider edge. All other ports (those not configured as access ports) are considered
VPLS network ports by default when MPLS/VPLS is enabled for the switch.
Access ports and networks ports differ in their level of support for other switch applications, as shown in
the following table:
Layer 2 Protocol Control Frames
By default, Layer 2 control frames are processed as follows:
How control frames are handled is configurable using Layer 2 port profiles. See “Configuring Layer 2
Profiles for Access Ports” on page 11-22 for more information.
Multiprotocol Label Switching (MPLS)
The LDP-based MPLS implementation described in the Chapter 10, “Configuring MPLS,” provides the
core MPLS network required to provision Virtual Private Network (VPN) services. VPLS is the only such
VPN supported to run over the OmniSwitch MPLS network at this time.
