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.

If technology migration on the network affects the services running on the live network, strictly follow the preset operation process and risk control measures during the implementation of the technology migration project. Generally, this type of project is defined as a migration project. Which of the following operations performed on the live network belongs to a non-migration project?

MPLS supports nesting of multiple labels. After receiving an MPLS packet, a device first processes the label next to the Layer 2 header, that is, the top MPLS label.

I-SPF and PRC can speed up ISIS route convergence. PRC does not calculate nodes. Instead, it updates routes based on the shortest path tree (SPT) calculated using the SPF algorithm.

OSPF requires that routers in the same area have the same link state database (LSDB). As the number of routes on the network increases, some routers cannot carry so much routing information due to limited system resources. This state is called database overflow. If the Isdb-overflow-limit number 7 command is run on all routers on an OSPF network, which of the following conditions are likely to cause routers to enter the overflow state?

On a broadcast network, routers (including non-DIS routers) of the same level on a network segment can establish neighbor relationships. In the implementation of BFD for IS-IS, however, BFD sessions are established only between a DIS and non-DIS routers, not between non-DIS routers.

BFD for OSPF refers to the association of BFD with OSPF to speed up OSPF's response to network topology changes. The OSPF neighbor relationship can enter the Full state only after the BFD session goes up. The OSPF neighbor relationship can go down only after the BFD session goes down.

On the OSPF network shown in the figure, area 1 is a stub area, area 2 is a totally stub area, and area 3 is an NSSA. Which of the following LSAs does not exist in areas 1, 2, and 3?

On the network shown in the figure, OSPF is deployed on R1 and R2. IS-IS is deployed on R2 and R3. To enable R1 to obtain the route to 10.0.3.3/32, ISIS routes are imported into OSPF on R2. In this case, the next hop address to 10.0.3.3/32 in the routing table of R1 is_____.
