VRF based design

Hi Guys,

I am working on one Enterprise network design where virutualization is main we decided for EVN but unfVortunately only 32 EVN are supported from cisco. We moved back to Old VRF technology.

Requirement for VRF is around 600 in numbers and its a entriprise network. My concern is whether VRF or VRF lite is good in this scenario.

Main concentration is some sets for vlans (EX: 2,3,4,5) vlans should mapped to one VRF  and so on. There is only two core swithes which need to run VRF that switches is also in VSS mode.

Its a collapsed core design and in the core two 650x in VSS mode and connected to 2960 switches. For sure 2960 has no VRF.

Planning to Layer 2 VLAN to the VRF in the core lets says VLAN 2,3,4,5 will have respective SVI interface and these will be mapped to VRF Red-Zone and VLAN 6,7,8.10 will be mapped to Green-Zone VRF.

Both the VRF will not have permissions to communicate with each other.

Main concept for this design is Traffic sepration. EVN was the good choice but has limitation only upto 32. so new which will be recommended design VRF or VRF Lite.

Please advice on above.

Thanks in Advance
