Which First Hop Router Protocol uses the virtual MAC address 0000.5E00.0101?

Which First Hop Router Protocol uses the virtual MAC address 0000.5E00.0101?

• A. GLBP
• B. HSRP
• C. VRRP
• D. GLBP and HSRP

Answer: (C)

In VRRP, the group presents a shared virtual MAC address that represents the virtual router. The virtual MAC follows the pattern 00-00-5E-00-01-XX, where XX is the VRID. The address 00-00-5E-00-01-01 is the VRID 1 virtual MAC, which is used by the master VRRP router to respond to traffic addressed to the virtual MAC. Other FHRP protocols use different MAC schemes, so this specific prefix and tail belong to VRRP. That’s why the correct protocol is VRRP.
