Configuring Switching Between Pseudowires Using VPLS Mesh Groups

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
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
To configure switching between Layer 2 circuit pseudowires using VPLS mesh groups,
you can do either of the following:
Configure a mesh group for each Layer 2 circuit pseudowire terminating at a VPLS
routing instance. The Junos OS can support up to 16 mesh groups on MX Series routers
and up to 128 on M Series and T Series routers. However, two mesh groups are created
by default, one for the CE routers and one for the PE routers. Therefore, the maximum
number of user-defined mesh groups is 14 for MX Series routers and 126 for M Series
and T Series routers.
Configure a single mesh group, terminate all the Layer 2 circuit pseudowires into it, and
enable local switching between the pseudowires by including the
statement at the
[edit routing-instances routing-instance-name protocols vpls
mesh-group mesh-group-name]
switching for mesh groups (except for the CE mesh group) because all of the VPLS PE
routers must be configured in a full mesh. However, local switching is useful if you are
terminating Layer 2 circuit pseudowires in a mesh group configured for an LDP signaled
VPLS routing instance.
NOTE: Do not include the
in a full mesh VPLS network.
To terminate multiple pseudowires at a single VPLS mesh group, include the
statement:

You can include this statement at the following hierarchy levels:

mesh-group-name]
