[c-nsp] Internet inside a VRF?

[Nick Ryce]

Does memory usage not increase by putting all the internet routes in a VRF?

Hi,
Putting internet in a vrf is not that bad. I agree with some people say that separate the global routing table with vrf is easier, especially for networks that are deploying MPLS routers from scratch. I don't see any advantages from putting internet Prefixes in the global routing table.

Best Regards,
