[c-nsp] FIB table saving technique

[Mack McBride]

This is definitely in the roadmap from discussions with Cisco.
However a firm date hasn't been given.
It appears to be fairly high priority as the routing table is growing and the 6500s and Nexus 7Ks
aren't going to get any larger TCAM (Stuck at 1M/0, 512K/256K, 640k/192K depending on how you chop it up).

Based on growth patterns the 512K mark is likely to be exceeded in 12 - 24 months.  The 640K mark is probably
18 - 36 months out.  I am planning on the 640K mark in about 24 months.
Larger IGP tables could already be pushing the 512K size limit.  I suspect we will see carriers dropping /24 de-aggregates if the routing table starts growing too fast.

Hi

On march 2011 I was on Cisco presentation "FIB table saving technique (with simple virtual aggregation)". Robert (author or presentation) said that this feature should be integrated in IOS version "RLS 11"
(which means around 15.2). But on release notes for 15.2 I cannot find this feature. Do any one know will Cisco implement this in near future ?
