• Question 15:

  As shown in the following figure, R1 can connect to the Internet through R2 or R3. EBGP connections are set up between R1 and R2 and between R1 and R3.

• Question 16:

  In the command, ipv4-address { mask | mask-length } [ as-set | attribute-policy route-policy-name1 ] detail suppressed | origin-policy route-policy-name2 | suppress-policy route-policy-name3 ] Parameters can be used to influence Summary The route and its result. What is correct about the command description?

  A. If configured, the Suppress policy Route-production clause can also be used to pick the suppressed route. policy if-match is fine, The clear route will still be advertised. Other Route-policy BGP will be given to neighbors.
