A. B. C. D. E.BCD
VRRP (Virtual Router Redundancy Protocol) is a protocol that provides redundancy for IP networks by allowing a group of routers to share a virtual IP address. Here are the correct statements about VRRP:
A. It requires speakers to be configured with BFD: This statement is incorrect. BFD (Bidirectional Forwarding Detection) is an optional protocol that can be used to improve the convergence time of VRRP. However, it is not required for VRRP to function.
B. It uses a virtual router MAC address for LAN communications: This statement is correct. VRRP uses a virtual MAC address, which is shared among the routers in the VRRP group. This virtual MAC address is used as the destination MAC address for all packets sent to the virtual IP address.
C. It uses multicast address 224.0.0.18: This statement is correct. VRRP uses multicast address 224.0.0.18 for communication between routers in the VRRP group.
D. It is confined to the local network with a TTL of 255: This statement is incorrect. VRRP packets can be routed between networks, and the TTL value is set by the router that generates the packet.
E. It uses the virtual router's lo0 address for LAN communications: This statement is incorrect. VRRP uses the virtual IP address for LAN communications, not the loopback address (lo0).
