What is the purpose of Route Target Constraint?

  1. A new Route Target definition is specified in RFC 4684. The Syntax differs from old syntax. The old syntax is a waste of processing power on the Route Reflector and PE and is waste of bandwidth.

  2. Route Targets are not attached to the VPNv4 or VPNv6 prefixes. Instead of using route targets, Route Distinguishers used to import and export VPNv4 and VPNv6 prefixes to and from VRFs.

  3. Route Reflectors send only wanted VPNv4 or VPNv6 prefixes. quot;Wantedquot; means the PE has VRF importing the specific prefixes.

  4. The Route Targets are constrained to one Autonomous System. The ASBR router strip all of the Route Target information that is contained in the VPNv4 or VPNv6 prefixes.

Answer: C
