• The Provider Edge and Route Reflector routers must run software supporting the same IETF draft version
of L2VPN Ethernet VPN (EVPN). Due to the differences in BGP Network Layer Reachability Information
(NLRI) encoding, later draft versions are not backward compatible with earlier ones. The following table
shows the supported draft for various Cisco IOS XR software releases.

Configuring Ethernet Flow Points on CNP and PNP Ports
Perform this task to configure an Ethernet flow point (EFP) on the customer network port (CNP) or the provider
network port (PNP).
SUMMARY STEPS
1. configure
2. interface type interface-path-id.subinterface l2transport
3. encapsulation dot1q vlan-id or encapsulation dot1ad vlan-id or encapsulation dot1ad vlan-id dot1q
vlan-id
4. Use the commit or end command.
DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Enters the Global Configuration mode.
Step 2 interface type interface-path-id.subinterface l2transport
Example:
RP/0/RSP0/CPU0:router(config)# interface
GigabitEthernet0/0/0/10.100 l2transport
Configures an interface for L2 switching.
Step 3 encapsulation dot1q vlan-id or encapsulation dot1ad vlan-id or encapsulation dot1ad vlan-id dot1q vlan-id
