RP/0/RSP0/CPU0:router(config-bgp)# address-family l2vpn mspw
Specifies the L2VPN address family and enters address family configuration mode.
Step 4 neighbor ip-address
Example:
RP/0/RSP0/CPU0:router(config-bgp)# neighbor 10.10.10.1
Adds the IP address of the neighbor in the specified autonomous system.
Step 5 address-family l2vpn mspw
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbr-af)# address-family l2vpn mspw
Specifies the L2VPN address family of the neighbor and enters address family configuration mode.
Step 6 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
EVPN Virtual Private Wire Service (VPWS)
The EVPN-VPWS is a BGP control plane solution for point-to-point services. It implements the signaling
and encapsulation techniques for establishing an EVPN instance between a pair of PEs. It has the ability to
forward traffic from one network to another without MAC lookup. The use of EVPN for VPWS eliminates
the need for signaling single-segment and multi-segment PWs for point-to-point Ethernet services. You can
also configure the PWHE interface and a bridge domain access pseudowire using EVPN-VPWS.
EVPN-VPWS single homed technology works on IP and MPLS core; IP core to support BGP and MPLS core
for switching packets between the endpoints.
Information About EVPN-VPWS Single Homed
The EVPN-VPWS single homed solution requires per EVI Ethernet Auto Discovery route. EVPN defines a
new BGP Network Layer Reachability Information (NLRI) used to carry all EVPN routes. BGP Capabilities
Advertisement used to ensure that two speakers support EVPN NLRI (AFI 25, SAFI 70) as per RFC 4760.
The architecture for EVPN VPWS is that the PEs run Multi-Protocol BGP in control-plane. The following
image describes the EVPN-VPWS configuration:
