What is L2VPN pseudowire?

What is L2VPN pseudowire?

L2VPN Pseudowire Switching allows the user to extend L2VPN Pseudowires across an inter-AS boundary. This feature connects multiple contiguous pseudowires to form an end-to-end multihop pseudowire. Network topology: One Pseudowire VC ID 1000 is established within MPLS-A network between PE1 and PE-AGG1 routers.

What is a pseudowire used for?

Pseudowire (PW) is an emulation of a wired connection. It is the emulation of various telecommunication or networking services such as edge-to-edge connection over packet-switching networks (PSN). It emulates the essential attributes of a packet-switching network such as ATM, Ethernet or Frame Relay.

What is a L3VPN?

Layer 3 VPN (L3VPN) is a type of VPN mode that is built and delivered on OSI layer 3 networking technologies. The entire communication from the core VPN infrastructure is forwarded using layer 3 virtual routing and forwarding techniques. Layer 3 VPN is also known as virtual private routed network (VPRN).

What is the difference between L2VPN and VPLS?

The virtual private LAN service (VPLS) is an MPLS-based Ethernet point-to-multipoint (P2MP) L2VPN service provided over a public network. VPLS ensures that geographically isolated user sites can communicate over MANs and WANs as if they were on the same LAN. VPLS is also called transparent LAN service (TLS).

What is the difference between VPLS and MPLS?

MPLS offers increased flexibility and scalability through the use of virtual private networks that automatically segregate traffic to optimise performance, while VPLS is ideal for organisations that want their in-house teams to enjoy complete control over their routing by combining LAN and WAN in a way that optimises …

Does XConnect support redundant pseudowire switchover?

… The Xconnect as a Client of Bidirectional Forwarding Detection (BFD) feature provides a trigger for redundant pseudowire switchover based on BFD’s fast failure detection capabilities. Your software release may not support all the features documented in this module.

What is the pseudowire-class configuration group?

The pseudowire-class configuration group specifies the characteristics of the tunneling mechanism, which are: Encapsulation type Control protocol Payload-specific options You must specify the encapsulation mpls command as part of the pseudowire class for the AToM VCs to work properly.

How to configure the XConnect command for different transport types?

For each transport type, the xconnect command is configured slightly differently. The following configuration steps use Ethernet VLAN over MPLS, which is configured in subinterface configuration mode. See Any Transport over MPLS to determine how to configure the xconnect command for other transport types. Enables privileged EXEC mode.

Does L2VPN pseudowire switching work with Cisco IOS XE?

In Cisco IOS XE Release 2.4, Pseudowire Switching is supported on Ethernet over MPLS attachment circuits. L2VPN Pseudowire Switching is supported with AToM.
