A. It is implemented on the user side, the implementation method is simple, the public network and the private network route are isolated, and it is safe and reliable.

B. Implemented on the user side, directly connect the CE to the Internet. Each user site can be individually connected to the Internet. That is, the CE of each site is configured to the default route of the Internet.

C. In the PE, realization is complex, and there are security risks, PE equipment may be subject to Internet of Dos political strike.

D. Implemented on PE. The PE device sends a default route to the Internet to the CE, and adds a default route to the VPN instance routing table to point to the Internet gateway.

Question #26

In the command aggregate ipv4-address {mask | mask-length} [ as-set | attribute-policy route-policy-name1 | detail-suppressed | origin-policy route-policy-name2 | suppress-policy route-policy-name3], multiple parameters can be used to influence the summary route and its results.
What is the correct description about this command? (Multiple Choice)

A. If As-set is configured, AS_ATH of the summary route contains AS path information of all specific routes to prevent routing loops.

B. If the Origin-policy is configured, only the detailed routes matching the Route-policy can participate in the aggregation.

C. If Attribute-policy is configured, you can change the attributes of the aggregated route.

D. If the Suppress policy is configured, the aggregated route is generated. The if-match clause of the route-policy is used to select the detailed route to be suppressed. The detailed route matching the route-policy is still advertised to other BGP neighbors.
