Assuming of course each block of address space is big enough to stand on it's own when compared with other's BGP filters (see other thread). If all the parts put together are big enough, but they're not big enough individually, as long as you're using the same transit provider in each location, you can ask them to aggregate the advertisement together for you to present to the rest of the world (which you should do anyway if you can to be a good Internet citizen). Of course, you'll need to make sure that you have default routes pointed out the transit connections in each site or you won't be able to get traffic to and from your other sites due to BGP loop detection. > Overlapping this space with isolated networks falls under the category > of bad mojo.
