Or until people who are still running multi-year old cisco code actually upgrade? This seems to primarily impact:
1) Old cisco code 2) PC based bgp daemons
Both of which likely just need to be upgraded. I actually suspect that a lot of people who dropped their bgp sessions did not notice something happened, and still will not upgrade their code. I searched the archives, some variations of this have happened since 2001. There's been a few PSIRT and other issues since then, I suspect these people don't even know they have a bgp speaking device anymore.
