JN0-663 · Question #151

Referring to the exhibit, you need to implement VPLS between CE-A1 and CE-A2. You must ensure that no loops are created due to the multihoming of the connection from CE-A2 to PE2 and PE3. Based on…

The correct answer is A. In a BGP VPLS, configure a primary and backup neighbor. D. In a BGP VPLS, configure multihoming and local preference on PE-2 and PE-3. If you want to enable multihoming for a VPLS routing instance, you cannot also enable LDP signaling. You can only enable BGP signaling. configuring-vpls-multihoming.html
