In the case of not dividing the area, which of the following description is true about the link state routing protocol? (Multiple Choice)

• A.Each router establishes a topological structure of the entire flood domain
• B.Each router learns the route directly from the routing update and adds it to the routing table.
• C.Routers in the flooding domain may repeatedly receive the same link state information.
• D.The router will send all the wrong path status information sent by one neighbor to all other neighbors to ensure the synchronization of the database.
• E.Routers in the entire flooding domain have the same wrong path state database

Regarding the introduction of routes, which of the following description is wrong?

• A.By default, the default metric of the external route redistributed by OSPF is 1, and the imported external route type is Type2.
• B.bgp supports both import and network when generating routes. Network mode is more accurate.
• C.After ISIS's level-2 network route is imported to the level-1 network, if the import policy is not manually configured, a routing loop is formed.
• D.Introducing IBGP routes in OSPF may cause routing loops.

Which of the following is the correct description of OSPF adjacency and link state database synchronization?

• A.The adjacency relationship starts from the EXSTART state.
• B.The INT status indicates that the router has received a Hello packet from the neighbor and the Hello packet already contains its own router ID.
• C.When the state of the OSPF router reaches the LOADING state, the FULL adjacency is formed.
• D.FULL adjacencies are formed between all routers in the broadcast network.

The configurations of the defined route-policy test are as follows:
ip community-filter 1 permit 100:1
ip as-path-filter 2 permit ^100$
route-policy test permit node 10
if-match community-filter 1
if-match AS-path-filter 2
apply as-path 200
Which of the following statements is true?

• A.The BGP routes will match the route-policy test only when they contain as-path 100. The as-path of the matched routes is then changed to 200.
• B.The BGP routes will match the route-policy test as long as they contain community attribute 100:1. The as-path of the matched routes is then changed to 200.
• C.The BGP routes will match the route-policy test only when they contain both community attribute 100:1 and as-path 100. The as-path of the matched routes is then changed to 200.
• D.The BGP routes will match the route-policy test only when they contain either community attribute 100:1 or as-path 100. The as-path of the matched routes is then changed to 200.

As shown in the following figure, in IPv4 and IPv6 environments the SEL value in an IS-IS NET address is always 00.

• A.False
• B.Ture
