EVPN MPLS Configuration
This chapter includes step-by-step configurations for EVPN MPLS for Single Homing and Multi Homing.
Overview
Ethernet VPN (EVPN) solution provides Ethernet multipoint services over MPLS networks. EVPN operates in contrast to the existing Virtual Private LAN Service (VPLS) by enabling control-plane based MAC learning. PEs participating in the EVPN instances learn customer MAC routes in control-plane using MP-BGP protocol. Control-plane MAC learning brings a number of benefits that allow EVPN to address the VPLS shortcomings, including support for multi-homing with per-flow load balancing.
In EVPN, PEs advertise the MAC addresses learned from the CEs that are connected to them, along with an MPLS label, to other PEs in the control plane using Multiprotocol BGP (MP-BGP). Control-plane learning enables load balancing of traffic to and from CEs that are multihomed to multiple PEs. This is in addition to load balancing across the MPLS core via multiple LSPs between the same pair of PEs. It also improves convergence times in the event of certain network failures.
Note: The EVPN will supported over static LSP, LDP,BGP-LU transports.
VPN Terminology
MAC-VRF: A virtual routing and forwarding table for storing MACs on a PE for specific bridge domain.
CE: Customer Edge device, e.g., a host, router, or switch.
PE: Provider edge device
EVI: An EVPN instance spanning the Provider Edge (PE) devices participating in that EVPN.
Note: Ethernet Segment (ES): Set of Ethernet links connected between CE and PE. Single CE can be connected to multiple PEs.
Ethernet Segment Identifier (ESI): A unique non-zero identifier that identifies an Ethernet segment is called an ESI
Ethernet Tag: An Ethernet tag identifies a particular broadcast domain, e.g., a VLAN. An EVPN instance consists of one or more broadcast domains.
Benefits
The EVPN control-plane MAC learning has the following benefits:
• Eliminate flood and learn mechanism as hosts are learned over control plane.
• OcNOS supports both dynamically learned hosts and statically configured hosts, which are advertised/learned over the EVPN control plane.
• Fast-reroute, resiliency, and faster convergence in case of multihoming
• Load balancing of traffic to and from CEs that are multihomed to multiple PE's.
The following EVPN types are supported:
• Single-homed CE: One CE is connected to One PE device.
• Multihomed CE: One CE is connected to Multiple PE devices. OcNOS supports dual-homed CEs with all- active multi homing mode.
Route Types
These EVPN route types are supported:
• Route Type 1: Ethernet Auto-Discovery (AD) Route
The Ethernet (AD) routes are advertised on per EVI and per ESI basis. These routes are sent per ES. They carry the list of EVIs that belong to the ES.
This route is advertised when multihomed CEs already exist.
• Route Type 2: MAC/IP Advertisement Route
The host's IP and MAC addresses are advertised to the peers within NLRI. The control plane learning of MAC addresses reduces unknown unicast flooding.
• Route Type 3: Inclusive Multicast Ethernet Tag Route
This route establishes the connection for broadcast, unknown unicast, and multicast (BUM) traffic from a source PE to a remote PE.
This route is advertised on per VLAN and per ESI basis.
• Route Type 4: Ethernet Segment Route
Ethernet segment routes enable to connect a CE device to two or PE devices.
Ethernet segment routes enable the discovery of connected PE devices that are connected to the same Ethernet segment.
EVPN auto route target will be supported under MAC VRF.
In EVPN-VPWS the auto-discovery of peer PE nodes is done with the pair of Ethernet A-D routes. Inclusive Multicast route does not have participation on auto-discovery unlike ELAN-EVPN VPLS. Since there is no mac-advertisement, MAC-IP route is not applicable
Note: Only Sub-interface supported as Access-port for EVPN-MPLS.

EVPN-MPLS L2CP Tunneling
EVPN-MPLS services shall support transparent L2 control plane protocol tunneling via network tunnels between CE's, via Sub-ifp framework support. The protocols which are tunneled are controlled by configuration at parent Interface (of A/C ports).The below list of L2 control plane BPDU shall be transparently tunneled across EVPN-MPLS networks based on egress tunnels when Tunnel action is configured.
• dot1x
• efm
• elmi
• lldp
• xSTP
• lacp
In case of action "DISCARD" and "PEER" appropriate behavior should see.
• PEER - the corresponding L2 control packet shall be uplifted to the CPU/control plane for processing.
• DISCARD - the corresponding L2 control packets are dropped at node.
Default behavior is PEER.
Topology
See Figure 25-1 and Figure 25-3.
Note: L2CP should be enabled in all PEs access interface to have end to end traffic.

EVPN-MPLS MAC Statistics
MAC Statistics feature provides statistics based on number of MAC's routes learned during ELAN and ETREE EVPN-MPLS service. Generic show command supported for both MH and SH services.
"show evpn mpls route-count" is used by admin to fetch all the three route type count (MAC-Only, MAC-IPV4, MAC-IPV6) for per VPN-ID of an EVPN MPLS service and/or route-type.
The details of routes can be fetched via "show evpn mpls nd-cache", "show evpn mpls arp-cache" and "show evpn mpls mac table".
MAC Statistics functionality is "Not Applicable" for EVPN E-LINE service as its point-2-point and does not have MAC advertisements functionality.
Topology
See Figure 25-1 and Figure 25-3.
Configurations
Refer to above configurations to bring up the EVPN service for both SH andMH. No specific configuration needed to get the show command output. Based on the installed service and traffic below route count will be fetched.

EVPN-MPLS Control-Word Support
A control-word is 4-byte optional field inserted between MPLS label stack & MPLS payload in data traffic as demarcation between MPLS labels & payload to distinguish a PW payload from an IP payload carried over the MPLS LSP, so that LSR or transit node which does deep packet inspection should not treat PW payload as IP payload and result in incorrect ECMP/load-sharing.
Some of salient points for support provided in OcNOS:
• control-word is applicable for both L2-EVPN (E-LAN, E-LINE etc) service data traffics and not applicable for L3-EVPN (IRB) traffic.
• control-word is based on static-CLI configurable along with any EVPN instance creation.
hardware-profile filter evpn-mpls-cw enable CLI must be configured for Control-word Support.
System requires reboot once after hardware profile filter control-word enabled.
Topology
See Figure 25-1 and Figure 25-3.
Note: Control-word should be symmetrically enabled/disabled across all PE nodes to have end to end non-malformed traffic handling.

EVPN-MPLS RSVP Multipath
EVPN-MPLS services with RSVP multipath as a transport provides, Multiple RSVP tunnels which are grouped in ECMP/Multipath group to do load sharing for better optimized and efficient usages of multiple RSVP trunks towards the same Destination.
At ingress node the traffic is load-balanced based on the configured hash (L3 src/dest IP/port, L2 src/dst mac, or in-label if intermediate Autonomous segments). Each LSP path within multipath group can provide individual protection for each path (facility, 1-to-1, secondary).
Each tunnel path in multipath group cost may vary (can have different hop, with consideration for load-balancing the traffic).
Unicast traffic is load shared across all the available multipath member (but not mandatory always) where as in case of BUM only the Active member carries traffic. Addition/deletion should not have impact in traffic in case of unicast, and switchover time is not guaranteed <50ms in case of BUM traffic.
This feature supports across all EVPN service as both SH and MH modes and only BUM Traffic not supported for ELINE service alone as per RFC standard.

EVPN-ELINE CFM Single Homing
CFM (as per IEEE 802.1ag 2007) provides capabilities useful for detecting, verifying and isolating connectivity failures in Virtual Bridged Local Area Networks through Continuity Check, Loop Back and Link Trace protocols. These capabilities can be used in networks operated by multiple independent organizations, each with restricted access to each other's equipment.
The network administrator is generally informed about the failure in the connection based on the reception of Continuity Check Messages or by the user. The administrator can then initiate Loop Back or Link Trace accordingly to quickly determine and then isolate the fault condition.
The CFM information is conveyed in Protocol frames called CFM Protocol Data Units (CFM PDUs). The CFM PDUs contain the appropriate control and status information used to detect, verify and isolate faults. It also contains information for path discovery in CFM-enabled links.
Currently, supported only for EVPN-ELINE Single home and up MEP service on both Q1 and Q2 platforms.
Topology
The diagram depicts the Single Homed topology for the EVPN MPLS configuration examples that follow.
