A. Multiple VRRP groups can be created on an interface of a router. The router functions as a master device of a VRRP group or a backup device of other VRRP groups

B. At least two virtual routers need to provide forwarding services simultaneously

C. Hosts in the same LAN need to be configured with different virtual routers as their default gateways

D. When configuring the priority, ensure that the same router functions as the master device for three VRRP groups

A. When sending a data packet with the destination IP address 4.4.4.4, the router sends it directly without any label added.

B. When sending a data packet with the destination IP address 33.3.3, the router adds label 1026 to the packet before sending it.

C. When sending a data packet with the destination IP address 2.2.2.2, the router sends it directly without any label added.

D. After receiving a data packet with label 1024, the router changes the label to label 1027 and then sends the packet.

A. RIPng supports a maximum of 32 hops. RIPng does not have an authentication mechanism.

B. RIPng uses the link local address to send update packets.

C. RIPng supports MD5 authentication.

D. Each RIPng update packet contains a maximum of 25 routes.

A. The routers in the entire flooding domain have the same road data.

B. Each router establishes a topology structure for the entire flooding domain.

C. The router will send all the existing road information to all other neighbors to send the wrong state to the
neighbor, and the data synchronization certificate.

D. The router in the flooding domain may repeatedly receive the same road information chain.

E. Each router directly routes from the routing update and adds it to the routing table.
