C.Multicast MAC address is composed of 23 bits.

D.The first six hexadecimal value of the multicast Mac address is 0x01005e.

Question 17

There are two MAC address learning modes in the VPLS: unqualified and qualified. In qualified mode, all VLANs are processed by the same VSI and they share the same broadcast domain or MAC address space.

Question 19

Which of the following statement are correct regarding TTL value in VRRP packet?

A.The TTL value must be 255 In normal VRRP packet.

B.By default, the VRRP packet with TTL value not equal to 255 will be dropped; On VRP, we can use some commands to disable the function of delecting TTL value.
