Full ACK! For the IDR we then can use perfect match lookups which
scale very well and pretty cheaply to many millions of table entries.
BGP scales very well too if you've got a decent cpu in your router.
Our OpenBGPD easily does 30 flapping constandly full-feeds with 1 million
Lets get pragmatic and realistic!
