Entries in a MAC address table are classified into dynamic, static, and blackhole entries. In addition, the MAC address table of a switch also contains service MAC address entries, which are typically converted from dynamic entries.
IPSG is a source IP address filtering technology based on Layer 3 interfaces. It prevents malicious hosts from forging authorized hosts ' IP addresses to access authorized network resources.
As its network scale expands, an enterprise plans to move scattered servers to the same equipment room for unified management. During hardware migration, network engineers do not need to perform device commissioning and therefore do not need to work out a migration solution.
On a BGP/MPLS IP VPN network, which of the following are carried when a PE advertises VPNv4 routes?
To support the processing and calculation of IPv6 routes, IS-IS adds a new NLPID to TLV 129. The NLPID is an 8-bit field that identifies network layer protocol packets. Which of the following is the NLPID of IPv6?
Service routes of an enterprise are transmitted on the network. Some configurations of PE1 and PE2 are shown in the figure. Which of the following LSAs may CE2 receive?
On an MPLS network, after an LSR receives a Hello message from a peer, the LSR establishes an LDP adjacency with the peer. The Hello message is sent in multicast or unicast mode.
On the OSPF network shown in the figure, the cost values of links are marked. IS-IS Auto FRR is enabled on R1. The primary path from R1 to 10.0.3.3/32 is R1 → R2 → R3, and the backup path is R1 → R4 → R2 → R3.
Is this statement TRUE or FALSE?
Huawei NetEngine AR6120 and AR6121 each have two slots for accommodating service interface cards, and the two slots can be combined into one.
An interface of a switch is in error-down state. A possible cause is that the average rate of broadcast packets received by the interface exceeds the upper threshold set by the administrator for storm control.
