Good day, all.
All of yours, I think, knows about connectivity problem with yandex services at 19 Aug 2011. According to comment of their IT team, it happend when all BGP routes was mistakenly redistributed in OSPF, which leed to memory overflow at routers like a snowball, one-by-one. As far as I know, there is only one way to avoid it - by limiting maximum number of OSPF routes in redistribute process (Cisco example http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/fsoredis.html) at ASBR, which explicity is Single Point of Failure(SPoF). What happens if it failed you've just read above.
So don't the respected community consider to make request for changing RFC to avoid such SPoF in future and give possibility to limiting maximum size of OSPF(or, wider, any IGP) routes at any OSPF-routers?
I beg my pardon if that subject are far from ENOG or my networking skills aren't enough to do such proposal conclusion.
