• A. network cannot be used with the corresponding policy.
• B. The route injected through the network must exist in the IP routing table.
• C. The injected route needs to strictly match the mask length in the IP routing table.
• D. By default, BGP does not publish any local network routes.

What mechanism does the IS-IS protocol use to ensure the reliability of neighbor relationship establishment on broadcast networks?

• B. Status synchronization
• C. Checksum

When the Hold Time parameter negotiated by the two BGP neighbors is 0, no Keeplive packet is sent.

As shown in the figure, an OSPF multi-process is configured on the RT1 router, wherein process 100 of RT1 establishes an OSPF neighbor through the backbone area with RT2, and process 200 establishes an OSPF neighbor through the backbone area with RT3.

Please select the wrong options:

• A. Because both RT1-RT2 and RT1-RT3 establish neighbors through the backbone area, the RT2 OSPF process has the LSA generated by the RT1 OSPF process.
• B. The router RT3 public network routing table has OSPF routes to RT1 and RT2 routers.
• C. The router RT1 public network routing table has routes to RT2 and RT3.
• D. The OSPF process on router RT2 can use process 100 and RT1 to establish neighbors.

Which of the following description about the need to pay attention to the configuration of the Stub area is correct?

• A. The backbone area can be configured as a Stub area.
• B. If you configure an area as a stub area, configure the stub area attributes for all routers in the area.
• C. The virtual connection can cross the Stub area.
• D. The ASBR may exist in the Stub area.
