What is VPLS mesh group?
A PE router mesh group consists of a set of routers participating in a VPLS routing instance that share the same signaling protocol, either BGP or LDP. Each VPLS routing instance can have just one BGP mesh group. However, two mesh groups are created by default, one for the CE routers and one for the PE routers.
What is VPLS ID?
A VPLS ID uniquely identifies a VPLS instance. VPLS IDs are used in the scenario where BGP is used to find remote PEs and FEC 129 LDP is used to establish PWs to the remote PEs. The local PE advertises a BGP update that includes the configured VPLS ID as an extended community attribute to the remote PE.
What is Juniper VPLS?
Virtual private LAN service (VPLS) is an Ethernet-based point-to-multipoint Layer 2 VPN. It allows you to connect geographically dispersed Ethernet LAN sites to each other across an MPLS backbone. The paths carrying VPLS traffic between each PE router participating in a routing instance are signaled using BGP.
What is VPLS in Alcatel?
Alcatel-Lucent’s VPLS service provides a bridged or switched Ethernet Layer 2 network. Equipment connected to SAPs forward Ethernet packets into the VPLS service. The 7750 SR participating in the service learns where the customer MAC addresses reside, on ingress SAPs or ingress SDPs.
How does Cisco VPLS work?
In VPLS, a packet originating within a service provider customer’s network is sent first to a customer edge (CE) device (for example, a router or Ethernet switch). It is then sent to a provider edge (PE) router within the service provider network. In contrast, a Layer 2 VPN forwards packets in point-to-point fashion.
What is network VPLS?
The virtual private LAN service (VPLS) is an Ethernet-based point-to-multipoint Layer 2 virtual private network (VPN) that enables you to connect geographically dispersed Ethernet local area network (LAN) sites to each other across an MPLS backbone.
What is the difference between MPLS and VPLS?
Many organizations implement MPLS since it can be scaled easily, is protocol-agnostic, and is capable of handling different kinds of traffic. VPLS solutions are more difficult to implement, but they also provide better performance, faster speeds, and better security.
What is Nokia VPLS?
Virtual Private LAN Service (VPLS), as described in RFC 4762, Virtual Private LAN Service (VPLS) Using Label Distribution Protocol (LDP) Signaling, is a type of virtual private network service that allows the connection of multiple sites in a single bridged domain over a provider-managed IP/MPLS network or a Layer 2 …
What are the differences between VPLS and VPN?
VPLS is a virtual private network (VPN) technology. In contrast to L2TPv3, which allows only point-to-point layer 2 tunnels, VPLS allows any-to-any (multipoint) connectivity. In a VPLS, the local area network (LAN) at each site is extended to the edge of the provider network.
When to use signaling statement in Junos OS?
In Junos OS Release 7.3 and later, the signaling statement replaces the unicast statement at the [edit protocols bgp group group-name family l2vpn] hierarchy level. You must use the signaling statement if you wish to configure VPLS domains and Layer 2 VPNs simultaneously.
What are the virtual ports for VPLS in Green?
In a VPLS routing instance named green, PE1 has a local interface fe-0/1/0 and a virtual port of vt-0/3/0.32770 (the virtual port is created dynamically on the Tunnel Services PIC when VPLS is configured). PE2 has a local interface fe-0/1/0 and a virtual port of vt-0/3/0.32771 in the same green instance.
How to add a VPLS to an Ethernet interface?
Include VLAN VPLS encapsulation at both the physical and logical interface levels. Be sure to use the same VLAN ID for all Ethernet interfaces that are part of a single VPLS instance. Finally, add the Fast Ethernet interface into a VPLS routing instance and specify the site range, site ID number, and site name.
