If a router ID is configured in both the system via and the BGP view, BGP uses the router ID configured in the BGP view because the BGP view takes precedence over the system view.
A router performs a lookup in its FIB table for a packet. If the tunnel ID in the matching entry is 0, the packet needs to be forwarded through a tunnel, such as an MPLS tunnel.
When receiving a packet, a router matches the packet against ACL rules. The ACL matching result is either Matched or Unmatched. If the matching result is Unmatched, which of the following are possible causes?
A campus network uses OSPF for network communication. The display ospf peer command is run on a router, and the command output is as follows:

A wide area network (WAN) is a remote network that connects local area networks (LANs) or metropolitan area networks (MANs) in different areas for communication purposes. It is typically used to interconnect campus networks or data center networks.

Which of the following statements are true about the BGP route?
On an RSTP network, if a port receives an RST BPDU and finds that its buffered RST BPDU is superior to the received RST BPDU, the port discards the received RST BPDU without responding.
OSPF networks are classified into four types of networks by link layer protocol. Drag the following link layer protocols to the corresponding network types.(Token is reusable)
As shown in the figure, VRRP is associated with a BFD session. When a backup device detects a fault through BFD, the backup device immediately assumes the master role after the Master_Down_Timer timer expires.
