Page 32: Layer 2 Theory And Standards Adherence
Ethernet is defined by the IEEE 802.3 international standard. It enables the connection of up to 1024 nodes over coaxial, twisted-pair, or fiber-optic cable. The Cisco ASR 9000 Series Routers support Gigabit Ethernet (1000 Mbps) and 10-Gigabit Ethernet (10 Gbps) interfaces.

Page 35: Ethernet Flow Point
(this is discussed later in the document). Ethernet Flow Point An Ethernet Flow Point (EFP) is a substream partition of a main interface. On Cisco ASR 9000 Series Routers, the EFP is implemented as an L2 subinterface with an encapsulation statement.
Page 36: Gigabit Ethernet Protocol Standards Overview
By leveraging the current Ethernet standard and the installed base of Ethernet and Fast Ethernet switches and routers, network managers do not need to retrain and relearn a new technology in order to provide support for Gigabit Ethernet.

Page 37: Ethernet Mtu
• IEEE 802.1ad Provider Bridges—This standard is a subset of 802.1q and is often referred to as 802.1ad. The Cisco ASR 9000 Series Routers do not adhere to the entire standard, but large portions of the standard's functionality are supported.
Page 38: Flow Control On Ethernet Interfaces
The flow control used on 10-Gigabit Ethernet interfaces consists of periodically sending flow control pause frames. It is fundamentally different from the usual full- and half-duplex flow control used on standard management interfaces. On the Cisco ASR 9000 Series Routers both ingress and egress flow control are off by default.
Page 39: Link Autonegotiation On Ethernet Interfaces
Also, you can bridge or tunnel the traffic by many ways from one or more of the router’s ingress EFPs to one or more egress EFPs. This traffic is a mixture of VLAN IDs, single or double (QinQ) encapsulation, and ethertypes.

EFP traffic from exiting the router. The Cisco ASR 9000 Series Routers allow for different VLANs on different ports within the same bridge domain. This allows a bridge to forward a packet out of a port not configured for the VLAN tag on the packet.
Page 42 An ordering precedence is used for how EFP matches are applied in hardware. The model is for matches that are more specific to be processed before matches that are less specific. L2VPN and Ethernet Services Configuration Guide for Cisco ASR 9000 Series Routers, IOS XR Release 6.3.x...

The EFP can be used to designate the frames belonging to a particular Ethernet flow forwarded in the data path. These forwarding cases are supported for EFPs in Cisco IOS XR software: L2VPN and Ethernet Services Configuration Guide for Cisco ASR 9000 Series Routers, IOS XR Release 6.3.x...

Policy Based Forwarding The Cisco ASR 9000 Series Routers allow a single MAC address to be mapped to a VLAN that is different from the port’s configured VLAN. To separate the traffic entering two different EFPs, you must define an EFP using the source VLAN tag and the source MAC address.

Interoperability Between Cisco IOS XR and Cisco IOS on VPLS LDP Signaling The Cisco IOS Software encodes the NLRI length in the fist byte in bits format in the BGP Update message. However, the Cisco IOS XR Software interprets the NLRI length in 2 bytes. Therefore, when the BGP neighbor with VPLS-VPWS address family is configured between the IOS and the IOS XR, NLRI mismatch can happen, leading to flapping between neighbors.

This module provides conceptual and configuration information for Multiple Spanning Tree Protocol on Cisco ASR 9000 Series Routers. Multiple Spanning Tree Protocol (MSTP) is a spanning-tree protocol used to prevent loops in bridge configurations. Unlike other types of STPs, MSTP can block ports selectively by VLAN.

Ethernet Bundle interfaces. Note that this includes the Port Fast, Backbone Fast, Uplink Fast and Root Guard features found in Cisco implementations of legacy STP, RSTP and PVST, as these are encompassed by the standard MSTP protocol. Cisco ASR 9000 Series Routers can operate in either standard 802.1Q mode, or in Provide Edge (802.1ad) mode.
Page 443: Bpdu Guard
BPDU Guard BPDU Guard BPDU Guard is a Cisco feature that protects against misconfiguration of edge ports. It is an enhancement to the MSTP port fast feature. When port fast is configured on an interface, MSTP considers that interface to be an edge port and removes it from consideration when calculating the spanning tree.
Page 444: Restrictions For Configuring Mstp
A subinterface with a default or untagged encapsulation will lead to an MSTP state machine failure. Access Gateway One common deployment scenario for Cisco ASR 9000 Series Routers is as an nPE gateway device situated between a network of uPE access devices and a core or aggregation network. Each gateway device may provide connectivity for many access networks, as shown in following figure.
Page 445: Overview Of Access Gateway
(as is typical) the majority of the traffic is between an access device and the core or aggregation network, and there is little if any traffic between the access devices. L2VPN and Ethernet Services Configuration Guide for Cisco ASR 9000 Series Routers, IOS XR Release 6.3.x...
Page 446 (so long as the configuration on each is consistent). This also means that different access networks can use different pairs of gateway devices, as shown in the following figure. L2VPN and Ethernet Services Configuration Guide for Cisco ASR 9000 Series Routers, IOS XR Release 6.3.x...

An Ethernet services access control list (ACL) consists of one or more access control entries (ACE) that collectively define the Layer 2 network traffic profile. This profile can then be referenced by Cisco IOS XR software features. Each Ethernet services ACL includes an action element (permit or deny) based on criteria such as source and destination address, Class of Service (CoS), or VLAN ID.
