I spoke too soon. I found this right after posting
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.1/20ew/configuration/guide/vrf.pdf
Switch(config-vrf)# rd
route-distinguisher
Creates a VRF table by specifying a route distinguisher.
Enter either an AS number and an arbitrary number
(xxx:y) or an IP address and arbitrary number
(A.B.C.D:y).
Step 5 Switch(config-vrf)# route-target
{export | import | both}
route-target-ext-community
Creates a list of import, export, or import and export route
target communities for the specified VRF. Enter either an
AS system number and an arbitrary number (xxx:y) or an
IP address and an arbitrary number (A.B.C.D:y).
Note This command is effective only if BGP is running.
Step 6 Switch(config-vrf)# import map
route-map
(Optional) Associates a route map with the VRF.
I just added different numbers and they came right up.
THANKS!

My guess is they are doing vrf-lite and using frame-relay or dot1q to
bring these 3 VRFs to you. Which means the RD (used for MPLS L3VPNs)
are only locally significant in the case of vrf-lite and are arbitrary
numbers. It would be nice if Cisco didn't require RD's for vrf-lite
cause they service no purpose.
Now the import and export statements in vrf-lite also serve no
purpose, but also not required. Interesting that they exist in the
config.
As long as no interfaces are configured with 'mpls ip' and you don't
have a 'address-family vpnv4' configured under BGP those values are
meaningless outside of the local router.
HTH,

I have 3 VRF's on a CE router:
ip vrf xxx-General
rd 1:10
route-target export 1:10
route-target import 1:10
!
ip vrf xxx-Guest
rd 1:30
route-target export 1:30
route-target import 1:30
!
ip vrf xxx-Voice
rd 1:20
route-target export 1:20
route-target import 1:20
I just got 3 new VRF's from the ISP confgured, and I'm wondering
what numbers I need to have for the 'rd' and 'route-target xxport'
commands...? Are these arbitrary, come from the ISP, or can I just
use 40, 50, and 60?
Thanks,
chris
