catalyst 6500 VS-S720-10G and VRF Capacity

[csco11665954]

Hi,

I have at the 6500 with vs-s720-10G. the datasheet say 1024 VRFs each populated with up to 700 routes/VRF for MPLS. MPLS in hardware to enable use of layer 3 VPNs and EoMPLS tunneling. Up to 1024 VRFs with a total of up to 256,000 routes per system.

I'am configurating 70 VRF with 883 routes with VRF-lite.

will it support this routes number ??

With your VRF-lite deployment you described, are you planning to run any dynamic routing protocols, or are all the routes static?  If you are using dynamic routing for these VRF lite instances, I would probably be worried about the number of IGP instances needed.  However, maybe someone else has run a high number of VRF lite / IGP instances like that and could share their experiences.

Another concern with a 70 VRF deployment using VRF-Lite is the operational overhead, especially if you are running end-to-end VRF-lite.  The Path Isolation Design Guide recommends as a rule of thumb no more than 10-15 VRF's when doing end to end VRF lite.

Good luck,
