Which of the following actions related to this MAC address mobility is performed?

In the exhibit,

Which of the following actions related to this MAC address mobility is performed?
A . CEI generates an update message to PEI withdrawing its MAC.
B . PEI generates an update message to remote PES identifying the new location of CEI.
C . PE2 advertises a MAC/IP route for MACI with a sequence number higher than that received from PEI.
D . PE3 waits to receive a data packet from CEI to update its FDB entry for MACI.

Answer: C

Explanation:

PE2 advertises a MAC/IP route for MAC1 with a sequence number higher than that received from PE1. This indicates that MAC1 has moved from PE1 to PE2 and triggers a MAC withdrawal message from PE1 to remote PEs. CE1 does not generate an update message to PE1 withdrawing its MAC, nor does PE1 generate an update message to remote PEs identifying the new location of CE11.
