It depends on how many links you want to get indexed. I personally prefer to let Google find them naturally. I know it can be hard but if you just continue to build more links everyday eventually google will be find your new links everday (if that makes sense)

However since you did ask how to get them indexed quickly here is what I used to do.

If you only have 10-15 links to index just submit them to a social network site like digg.

If you have more than that then create a page with a list of all your links like on a web 2.0 platform. Submit the web 2.0 to a few social networking sites and when Google finds your web 2.0 it will also find all the links. Remember to delete the links within 48 hours or your web 2.0 will get banned and sometimes so can your i.p. It's better still if you have a spare website to do this.

Good Luck
