what i was asking is, what happens when:
- IGP route is not stable at this point (*)
- someone try to establish TCP to the (IGP) anycast address
- first packet goes to server A, and second goes to server B
(*) may mean that the provider is in unstable state:-)
anyway, the technique is just for short-lived transaction, just as
stated in the draft.
