Hmm, that makes sense. The AS Path should include both AS numbers in the export policy.

I believe it is 65540 1 because of the export policy shown in the image.

This seems like a tricky one. I'm going to go with C) 65540 65540, since the export policy shows that the aggregate route will include the AS number twice.

I think you're on the right track. The AS number is repeated in the export policy.

Hmm, I'm not sure. I was thinking D) 65550 65540, since the aggregate route is being advertised to an eBGP peer in AS 65550.

I think the correct answer is B) 65540 1. The aggregate route will include the AS number of the router that originates it (65540), plus the AS number of the peer router (1).
