Question # 95

Assume there are two VPLS services configured on the MDU. How could load-balancing be achieved when using Active/Standby pseudowires?

Options:
A.

This cannot be done.

B.

Each VPLS will use the same pair of SDP's with the same endpoint configured with the option "load-balancing 2".

C.

Each VPLS will need their own pair of spoke-SDP's configured. The spoke-sdp's that are to be active should be configured with the option "precedence primary".

D.

Under the end-point configuration, enable load-balancing 2 and the MDU will load balance automatically.

B.

Only after receiving LACP packets.

C.

Every 1 second.

D.

Never.

B.

BGP sessions established between RR1 and the PEs support the IPv4 address family only.

C.

BGP sessions established between RR1 and the PEs support IPv4 and VPN-IPv4 address families.
