The correct answer is A. Set the identifier type 11.12.11.12.11.12.11.12.11 on the PEX and PEY routers. For EVPN multihoming with Ethernet Bundles, all PEs attached to the same multihomed CE must share the same Ethernet Segment Identifier (ESI). In this case, PEA is already configured with identifier type 0 11.12.11.12.11.12.11.12.11. To achieve load balancing and redundancy, PEX…
Question
Refer to the exhibit. A network engineer with an employee ID: 5100:21:535 must configure routers PEA and PEB so that traffic between CE1 and CE2 is multihomed and load-balanced. The two 10GE links in Ethernet bundle 10 are sending traffic at different rates. Which action must the engineer take on PEX and PEY to complete the configuration?
Exhibit
Options
- ASet the identifier type 11.12.11.12.11.12.11.12.11 on the PEX and PEY routers.
- BChange the source and destination AC values to 5 and 6 respectively.
- CSet the identifier type 33.34.33.34.33.34.33.34.33 on the PEX and PEY routers.
- DSet the neighbor evpn vpi value to 200 on the PEX and PEY routers.

Explanation
For EVPN multihoming with Ethernet Bundles, all PEs attached to the same multihomed CE must share the same Ethernet Segment Identifier (ESI). In this case, PEA is already configured with identifier type 0 11.12.11.12.11.12.11.12.11. To achieve load balancing and redundancy, PEX and PEY must be configured with the same ESI value. This ensures that the Ethernet Segment is recognized as a single multihomed link and enables all-active forwarding.
