We keep Internet routes in the global table on all routers
we operate. Different routers have different capabilities
when it comes to how many routes they can hold in a VRF, or
how many VRF's they can have with a fixed number of routes
We also want to avoid putting too much reliance on MPLS for
basic services like Internet access. We relegate MPLS-based
services to those that MUST have it to work, e.g., BGP-
MVPN's, l2vpn's, l3vpn's, VPLS, e.t.c. Anything else that
doesn't really need MPLS lives on its own, e.g., IPv6 (no
need for 6PE), Internet access, e.t.c.
Keeping it really stupid is what we're after :-).
