[c-nsp] Full Internet Table in VRF

[Erich Borchert]

Hello,
I am wondering everyone's opinion on creating vrf's with the full
internet table in them.  VRF X for all peers and VRF Y for inexpensive
peers, on cisco 7600's with pfc3bxl.  The global table will be very
small just igp routes to reach the BGP next-hop addresses of a PE and
each vrf with carry full tables.  When Customer A in vrf X needs to
communicate with Customer B in vrf Y we create an import map on vrf X
allowing prefix's from Customer B to be imported into vrf X's table, and
conversely on vrf Y.  I am wondering if the pfc3bxl can handle 600,000
routes IPV4 + MPLS without croaking.  (I know the product documentation
claims one million of ipv4 routes).

Ideally, if the 7600 supported the import/export from vrf to global
table and vice versa we could accomplish this with a default global
table of all peers and one vrf for cheap peers.
