Juniper JUNOSE, Configuration Manual

Page: 615 / 738

To modify their pseudowires, the peer routers correct their MPLS forwarding tables
and set up new entries in their pseudowire tables.
VPLS Supported Features
The JUNOSe implementation of VPLS provides the following features:
■
Single-level VPLS hierarchy within a single autonomous system (AS) using MPLS
tunneling technology for the core
■
Support for the following types of network interfaces between the PE router and
the CE device:
■
Bridged Ethernet over ATM1483 subinterfaces
■
Fast Ethernet
■
Gigabit Ethernet
■
10-Gigabit Ethernet
■
VLAN and S-VLAN subinterfaces over bridged Ethernet, Fast Ethernet, Gigabit
Ethernet, or 10-Gigabit Ethernet interfaces
■
Autodiscovery of VPLS instance members using MP-BGP
■
VPLS signaling using MP-BGP to set up and tear down the pseudowires that
constitute a VPLS instance
■
VPLS signaling using LDP and the PWid FEC element (FEC Type 128) to set up
and tear down the pseudowires that constitute a VPLS instance
■
Interworking of the VPLS instance and the VPN routing and forwarding instance
(VRF) using an external cable connection
■
Multihoming
■
Class of service (CoS)
■
Inter-AS option A, inter-AS option B, and inter-AS option C services
■
Minimal filtering and policing support
As with L2VPNs, VPLS does not support BGP multipaths.
VPLS Platform Considerations
VPLS is supported on all E Series routers.
Module Requirements
You can configure VPLS network interfaces on all E Series module combinations that
support transparent bridging. The VPLS virtual core interface can exist on all E Series
module combinations that support MPLS tunnels.
