The correct answer is A. PE1(config)#12vpn. For single-homed EVPN-VPWS on IOS XR, you must tie a P2P pseudowire to the EVPN control plane by creating an L2VPN XConnect group with the p2p evpn construct. The key steps you still need on PE1 are: Enter the l2vpn xconnect group context. Define a p2p evpn1 pseudowire service…
Question
Refer to the exhibit. A Cisco engineer at a service provider must implement single-homed EVPN- VPWS. When router PE1 receives an EVPN per EVI EAD route from PE2, it must add the entry to its local Layer 2 RIB. The engineer began the implementation process by applying this configuration to PE1. Which additional configuration must the engineer apply to PE1 to complete the EVPN-VPWS implementation?
Exhibit
Options
- APE1(config)#12vpn
- BPE1(config)#12vpn
- CPE1(config-evpn)# interface Bundle-Ether10
- DPE1(config)#12vpn

Explanation
For single-homed EVPN-VPWS on IOS XR, you must tie a P2P pseudowire to the EVPN control plane by creating an L2VPN XConnect group with the p2p evpn construct. The key steps you still need on PE1 are: Enter the l2vpn xconnect group context. Define a p2p evpn1 pseudowire service instance. Bind your customer-facing interface to that PW. Under that interface, use neighbor evpn evi 100 target 12 source 10 to point it at the EVI and RT/VRF learned via MP-BGP. That configuration completes the EVPN-VPWS setup so that incoming EAD routes install in the L2RIB and push traffic out your GigabitEthernet1/0/1 interface.
