Which of the following statements about routing imports is correct? (Multiple choice)

When implementing route import, you can also deploy route air control, so as to realize the flexible control of correct business traffic

By importing routes, routing information can be transferred between different routing protocols

The routing protocol itself has the anti-loop feature, so there is no need to consider the loop problem when the routes enter each other.

NEW QUESTION 276
Regarding the load sharing description of VRRP, which is correct? (Multiple choice)

The load sharing method refers to the establishment of two or more backup groups, and multiple routers carry services at the same time

When configuring priority, the VRRP masters of the three virtual routers can be on different routers

Multiple virtual routers can be created on one interface of the router, so that the router can be used as the Master router in one virtual router, and at the same time as the Backup router in other virtual routers

The load sharing method means that multiple routers undertake business at the same time, so the load sharing method requires two or more virtual routers

NEW QUESTION 288
Will setting the community attribute of the route through the routing policy affect the route selection?

It can be indirectly affected. You can classify routes by setting the Community attribute of the route, and then set different routing-related attributes according to the category, such as Local_Pre, MED, etc., so as to achieve the purpose of influencing routing

It cannot be affected because the Community attribute of the route is a non-transitional attribute and cannot be transmitted between routers

It can be indirectly affected. You can classify routes by setting the community characteristics of routing, and then set different routing-related attributes according to the category. These attributes only include Loacal_Pre and MED, so as to achieve the purpose of influencing the routing

After the router receives the route update with the Commmity attribute of No_ Advertise, it will not be published outside the local AS

NEW QUESTION 289
