A company purchased private lines from two operators. In order to optimize the lines, the company
used the 6GP protocol to learn from two
Route entries that operate off. However, after the enterprise found that this configuration, the traffic
of the port route increased greatly, and the network engineering arrangement
After investigation, it was found that the traffic of the two operators was passed to each other
through the enterprise egress router. Therefore, the enterprise intends to use the routing strategy so
that the traffic of the packets of different carriers is no longer passed to each other. Is the
configuration in the following figure correct?

• A. True
• B. False

The routing policy tools that can be used by BGP mainly include Filterpolicy and oRoute-policy.
Fiterpolicy can only filter routes, Rote - policy can only modify routes

• A. True
• B. False
