MPLS TE event logging

Added support for logging the LSP and FRR events

7.3(0)D1(1)

Chapter 11, “Logging Label Switched Path (LSP) Events”

Chapter 11, “Logging Fast Reroute (FRR) Events”

MPLS TE Cost Limit

Added support for configuring cost limit for TE tunnels.

7.3(0)D1(1)

Chapter 11, “Configuring Cost Limit”

InterAS Option B

This feature was enhanced with the InterAS option B and InterAS option B (with RFC 3107) provisions. An IBGP VPNv4/v6 session between DC edge routers and an EBGP VPNv4/v6 session between DC edge routers and WAN routers can be established without a per VRF iBGP session between DC edge routers..

7.2(0)D1(1)

Chapter 26, “InterAS Option B”

Configuring Automatic Bandwidth Adjustment for MPLS TE Tunnels

Added information about automatic bandwidth adjustment for MPLS TE tunnels.

6.2(6)

Chapter 12, “Configuring Automatic Bandwidth Adjustment for MPLS TE Tunnels”

Any Transport over MPLS

Added Any Transport over MPLS (AToM), which accommodates different types of Layer 2 packets, including Ethernet and VLAN, to enable the service provider to transport different types of traffic over the backbone and accommodate all types of customers.

6.2(2)

Chapter 27, “Configuring Any Transport over MPLS”

Any Transport over MPLS Pseudowire provisioning

Added pseudowire provisioning for AToM. This feature enables you to configure static pseudowires in cases where you cannot use directed control protocols, such as the Label Distribution Protocol or Resource Reservation Protocol over traffic-engineered tunnels (RSVP-TE).

6.2(2)

Chapter 28, “Configuring Any Transport over MPLS Pseudowire Provisioning”

Ethernet over Multiprotocol Label Switching

Added Ethernet over Multiprotocol Label Switching (EoMPLS), which is a Virtual Private Wire Service (VPWS) that is used to carry Layer 2 Ethernet frames over an MPLS network. EoMPLS enables service providers to offer emulated Ethernet services over existing MPLS networks.

6.2(2)

Chapter 29, “Configuring Ethernet over MPLS”

EoMPLS Graceful Restart

Added support for a switch that is configured with the Label Distribution Protocol (LDP) Graceful Restart (GR) to assist its neighboring switches recover gracefully from an interruption in service.

6.2(2)

Chapter 30, “Configuring EoMPLS Layer 2 VPN Graceful Restart”

Layer 2 and Layer 3 load balancing co-existence

Added Layer 3 VPN and Layer 2 VPN forwarding that is performed independently on the switch using two different types of adjacencies. The forwarding is not be impacted by having a different method of load balancing for the Layer 2 VPN.

6.2(2)

Chapter 24, “Configuring MPLS Layer 3 VPN Load Balancing”

MPLS LSP Ping/Traceroute for LDP/TE and LSP Ping for VCCV

Added support for Virtual Circuit Connectivity Verification (VCCV) in Layer 2 VPN Operations, Administration, and Maintenance (OAM).

6.2(2)

Chapter 35, “Verifying Connectivity with MPLS LSP Ping and Traceroute”

MPLS over GRE

Added a mechanism for tunneling Multiprotocol Label Switching (MPLS) packets over a non-MPLS network.

6.2(2)

Chapter 25, “Configuring MPLS over GRE”

OSPF Sham-Link Support for MPLS VPN

Added a sham-link to connect VPN client sites that run Open Shortest Path First (OSPF) and share back door OSPF links in a Multiprotocol Label Switching (MPLS) VPN configuration.

6.2(2)

Chapter 22, “Configuring MPLS Layer 3 VPNs”

Virtual Private LAN Service

Added a point-to-multipoint service between multiple customer sites using a mesh of point-to-point pseudowires over the provider core to emulate a LAN between the sites.

6.2(2)

Chapter 31, “Configuring Virtual Private LAN Service”

VPLS VPN Pseudowire Redundancy

Added support for detecting a failure in the network and rerouting the Layer 2 service to another endpoint that can continue to provide the service.

6.2(2)

Chapter 32, “Configuring Layer 2 VPN Pseudowire Redundancy”

VPLS Dual-Homing with a vPC

Added support for integrating Virtual Private LAN (VPLS) with the virtual port channel (vPC) functionality in active-standby mode.
