I am looking at using MPLS and ip vrf forwarding to terminate multiple
VPNs on a CE router and then break each VPN out onto a physical
interface. I need to do this rather than simply doing rd imports as we
need firewalls between each VPN on the customers side.
Someone told me that there is a supported limit of 5 VRF's on the
CE side after that there is a CPU hit and the TAC will not support
it. However I can not find any reference to this on CCO. Anyone
care to comment , as I am assuming that there is no such limit on
the PE's or is my understanding of the VRF concept totally wrong ?
Also an interesting question is running non routeable and non DLSW'able
protocols over a Public MPLS cloud. Bridging over a tunnel would
be perfect but not supported. Martini over the MPLS is a bit bleeding edge
and it would mean a seperate VPN for the non routeable traffic. Any
comments most welcome ?
Regards,
Kevin
