Been discussing this with people and reading up, would like people's thoughts on whether or not its worth running IPv6 in a VRF or just let it loose in the global routing table.
Even though presently we use a VRF topology for various reasons, for IPv6 I am strongly on the side of running it natively - resource consumption (thinking of full internet routing tables in IPv6 in a VRF, yech) - no more multiple routing processes per router - lots of our present HW that is not going to go EOL in the next year or two struggles with IPv6 in a VRF (3750, 3560)
For purposes of 'mimicking' VRF separation for areas that require it going to bite the bullet and put firewalls where I need, the only alternative (short of mirroring the present VRF topology) is to go to a nightmare of tunnels and PBRS
I guess the penny dropped when reading about IPv6 on MPLS 6PE.
Thoughts appreciated (especially the ones telling me I'm wrong! its how I learn lol)
