Virtual private LAN service (VPLS) allows you to provide a point-to-multipoint LAN
between a set of sites in a virtual private network (VPN).
NOTE: In ACX Series routers, VPLS configuration is supported only on
ACX5048 and ACX5096 routers.
To configure VPLS functionality, you must enable VPLS support on the provider edge
(PE) router. You must also configure PE routers to distribute routing information to the
other PE routers in the VPLS and configure the circuits between the PE routers and the
customer edge (CE) routers.
NOTE: In the VPLS documentation, the word router in terms such as PE router
is used to refer to any device that provides routing functions.
Each VPLS is configured under a routing instance of type
can transparently carry Ethernet traffic across the service provider's network. As with
other routing instances, all logical interfaces belonging to a VPLS routing instance are
listed under that instance.
In addition to VPLS routing instance configuration, you must configure MPLS
label-switched paths (LSPs) between the PE routers, IBGP sessions between the PE
routers, and an interior gateway protocol (IGP) on the PE and provider (P) routers.
By default, VPLS is disabled.
Many configuration procedures for VPLS are identical to the procedures for Layer 2 VPNs
and Layer 3 VPNs.
