The following describes the behavior of mesh groups in regards to BGP-signaled PE
routers and LDP-signaled PE routers:
BGP-signaled PE routers—Automatically discovered PE routers that use BGP for
signaling are associated with the default VE mesh group. You cannot configure the
Junos OS to associate these routers with a user-defined VE mesh group.
LDP-signaled PE routers (FEC 128)—PE routers statically configured using FEC-128
LDP signaling are placed in a default mesh group. However, you can configure a VE
mesh group and associate each LDP FEC-128 neighbor with it. Each configured VE
mesh group contains a set of VEs that are in the same interior gateway protocol (IGP)
routing instance and are fully meshed with each other in the control and data planes.
LDP-signaled PE routers (FEC 129)—Configuration for a mesh group for FEC 129 is very
similiar to the configuration for FEC 128.
Note the following differences for FEC 129:
Each user-defined mesh group must have a unique route distinguisher. Do not use
the route distinguisher that is defined for the default mesh group at the [edit
routing-intances] hierarchy level.
Each user-defined mesh group must have its own import and export route target.
Each user-defined mesh group can have a unique Layer 2 VPN ID. By default, all the
mesh groups that are configured for the a VPLS routing-instance use the same Layer
2 VPN ID, the one that you configure at the [edit routing-instances] hierarchy level.

Router
This example shows how to configure the hierarchical virtual private LAN service (H-VPLS)
using different mesh groups to provide H-VPLS functionality and provides steps for
verifying the configuration. This is one type of H-VPLS configuration possible in the Juniper
Networks implementation. For information about the alternate type of configuration see
“Example: Configuring LDP-Based H-VPLS Using a Single Mesh Group to Terminate the
Layer 2 Circuits” on page 1304.
Using mesh groups improves LDP-based VPLS control plane scalability and avoids the
requirement for a full mesh of LDP sessions. This example uses BGP-based VPLS.
This example is organized into the following sections:
