Tien,

Apply PAT at the VRF to global transition. If it needs to be two way
communication between customers then you would need to do static NAT if you
have overlapping address space.

Subject: another mpls route leaking question

Hi GS,

When doing route leaking from vrf to global and back, we need to have the
vrf route in the global table, this so the return traffic from the global
now how to get to the vrf.
Ok, the questons I have:
so what happend if i have to overlapping customer who has the same subnet?
Is it the best practice to route the customer vrf route in the global route
table?(SP CORE)

Thanks for the help

Tien

Sample config:

ip route 10.15.53.0 255.255.255.0 Serial2/0
ip route vrf MAIN 125.70.0.0 255.255.255.0 FastEthernet0/0 125.50.23.2
global
