[f-nsp] Netiron 5.6 feedbacks

Fri May 23 14:01:03 EDT 2014

As my colleague Markus already mentioned, 5.6c is seriously broken.

We (Init7 / AS13030) run 5.5d on most boxes (XMR, MLXe, CER) with full mesh iBGP (about 40 neighbors), hundreds of eBGP, both v4/v6, OSPF and MPLS really stable for months. If you are good with the 5.5 feature set and want to be on the safe side go for 5.5d.
