Based on the local label allocation filtering failure, which subnet of prefixes must be selected to meet these requirements?

  1. CE loopbacks only that are used as BGP next hop

  2. PE loopbacks that are used as BGP next hop

  3. RR, P , and PE loopbacks that are used as BGP next hop

  4. all /32 prefixes advertised in the IGP

Answer: B
