And your assumption about my Ottawa-Toronto link is wrong. I have a 100M point-to-point ethernet link between the cities. I have a 100M transit connection to Peer1 in Toronto, and have issued a letter of intent to a transit provider in Ottawa for a 100M link.
Ralph, if you have a 100m link between the two cities, why don't you use conditional announcements to only announce your /20 though Ottawa if your primary transit in Toronto goes down? Then, you only need to announce your /20 in Toronto, no need to deaggregate, and the whole issue is solved.
Then, when you have the Ottawa 100m transit link up, you can announce your /20 to both transit providers all the time.
That is roughly the intention. I also have to be able to announce the more specifics for when the Ottawa-Toronto link goes down. You could find in the archives my posts from a couple months back asking how to do this. -Ralph
