Description
Specify the virtual private LAN service (VPLS) mesh group. The statement options allow you to specify each provider edge (PE) device that is a member of the mesh group. This statement is also used in the configuration of inter-autonomous system (AS) VPLS with media access control (MAC) operations.
When you configure mesh groups on the ACX7100-32C, ACX7100-48L, ACX7332, ACX7348,
ACX7509, ACX7024, and ACX7024X routers, you must also enable the system profile by
including the set system packet-forwarding-options system-profile
vpls-meshgroups statement on the ACX router. Upon issue of this
command, the packet forwarding engine (PFE) restarts.
The ACX7000 routers have the following limitations when you configure hierarchical VPLS (H-VPLS) mesh groups:
-
Control word for EVPN MPLS multihoming is not supported.
-
Penultimate Segment Pop (PSP) on SRv6 is not supported.
-
VXLAN stitching is not supported.
-
Up to 3 mesh-groups with no-local switching in a single VPLS routing instance.
-
A total maximum of 14 mesh-groups with either local switching or no-local switching per routing instance.
When you configure hot-standby redundant pseudowires in an H-VPLS hub-and-spoke
network, we recommend that you also enable
vpls-hot-standby-convergence. With VPLS hot-standby
convergence, the device advertises two different labels (L1 and L2 ) to its
neighbors. The device sends the L1 advertisement to the primary neighbor and the L2
advertisement to the backup neighbor. This allows a spoke device to differentiate
between messages sent by the primary pseudowire node from messages sent by the
backup pseudowire node. This reduces traffic sent and improves network convergence
when there is a transition from the primary pseudowire to the backup pseudowire. To
enable VPLS hot-standby convergence, include
vpls-hot-standby-convergence at the [edit
routing-options forwarding-table] hierarchy level on all the spoke
devices.
You can configure the no-local-switching option at the
[edit routing-instances routing-instance-name]
or the [edit logical-systems logical-system-name
routing-instances routing-instance-name]
hierarchies to disable local switching in a routing instance with VPLS.
If you set this option, you can’t set the local-switching option
under a VPLS mesh group to enable local switching only for a particular VPLS
mesh group. The instance-level no-local-switching statement
overrides the per-mesh-group local-switching setting.
