Viewing MPLS VPNs

The following topics provide an overview to Multiprotocol Label Switching (MPLS) virtual private network (VPN) technologies displayed by Cisco Active Network Abstraction (Cisco ANA) including the MPLS service view, business configuration, and maps:

•Supported MPLS and VPN Technologies and Routing Protocols, page 1-1—Provides an overview to MPLS VPN technologies supported by Cisco ANA.

•MPLS VPN Maps Overview, page 1-2—Provides an overview of MPLS VPN maps.

•VPN Business Configurations, page 1-2—Provides an introduction to the Layer 2 and Layer 3 VPN business configurations and available business elements.

•VPN Topology Connections, page 1-3—Describes Layer 2 and Layer 3 VPN map topologies.

For a more detailed description of the Cisco ANA NetworkVision window, menus, and toolbars, and working with tables, see the Cisco Active Network Abstraction 3.6.6 User Guide.

Supported MPLS and VPN Technologies and Routing Protocols

Cisco ANA supports the following technologies:

•MPLS.

•Border Gateway Protocol (BGP) including route reflector scenarios.

•Layer 3 BGP MPLS VPNs as defined in RFC2547.

•Label Distribution Protocol (LDP).

•Interior Gateway Routing Protocol (IGRP).

•Cisco IGRP.

•Extended IGRP.

•Pseudowire end-to-end emulation tunnels as defined in RFC3985 and implemented for Cisco Any Transport over MPLS (AToM). Pseudowire support is based on the Luca Martini drafts (draft-martini-l2circuit-encap-mpls-03.txt and draft-martini-l2circuit-trans-mpls-07.txt).

Note Cisco ANA supports payload types packet and cell only. For more information, see RFC3985, Section 3.3.

•MPLS traffic engineering based on RFC2702 with Resource Reservation (RSVP) protocol for signaling as described in RFC3209.
