Based on the illustration of the VPLS topology shown in the exhibit, which statement is true?
A.
PE-C must have a spanning-tree protocol enabled
B.
CE-C must have BGP enabled
C.
Traffic forwarded from PE-C to PE-A is forwarded on to PE-B
D.
Traffic forwarded from PE-C to PE-A is not forwarded on to PE-B
A. is the correct answer.
Yes i would say A also
there is many option to avoid loop for connection between PE-C and CE-C “spanning-tree not Must”
but the action that must done “if Traffic forwarded from PE-C to PE-A it will not forwarded on to PE-B”
so D is the more correct answer
Yes man you are right because of the split horizon rule.
