Q21. You are providing a customer two VPLS services in two different Metro networks. VPLS 500 has been configured in Metro 1 and VPLS 900 has been configured in Metro 2. The customer has requested that they have connectivity between the Metro Networks with their existing VPLS services. Which configuration on the PE routers linking the metro networks will allow for VPLS 500 and VPLS 900 to act as a single VPLS service? SDP 999 exists between the metro networks. Assume default values for all VPLS parameters. 

A. Metro 1>service#vpls 500 Metro 1>service>vpls# spoke-sdp 999:500 Metro 2>service#vpls 900 Metro 2>service>vpls>spoke-sdp 999:500 

B. Metro 1>service#vpls 500 Metro 1>service>vpls# mesh-sdp 999:500 Metro 2>service#vpls 900 Metro 2>service>vpls>mesh-sdp 999:500 

C. Metro 1>service#vpls 500 Metro 1>service>vpls# spoke-sdp 999:500 Metro 2>service#vpls 900 Metro 2>service>vpls>spoke-sdp 999:900
