A.Only when the BGP route carries the community attribute value of 100:1 or the AS-PATH is 100, The BGProad will match the aboveroute The AS-PATH attribute of the -policy matching route will be changed to 200

B.Only when the BGP route carries the community attribute value of 100:1 and the AS- When PATH is
100, the BGP route will match the aboveThe AS-PATH property of route-policy matching routes will be changed to 200

C.Only when the BGP route carries an AS-PATH of 100, the BGP route will match the aboveroute-policy.
AS_ that matches the route The PATH property will be changed to200

Question 62

in command aggregateate ipv4-address { mask | mask-length } [as-set I attribute-policy route-policy-name1 ldetail- suppressed I origid-policy route-policy-name2 |suppress-policy route-policy-name3], multiple parameters can be used toAffects summary routes and their results. Which description is correct about this command?

A.If Supp is configuredress-policy also generates aggregated routes. The if-match clause in Route-policy is used to select suppressed detailed routes. Detailed routes matching the Route-policy will still be advertised to other BGP neighbors

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

D.If Attrbute-policy is configured, you can change the attributes of the aggregated route
