In your PE(BORDER) send the traffic back to PE1 and in PE1 send the traffic
to the CE interface.

Subject: route leaking from global to vrf when there is no VRF interfaces.
HI group.
Im having a simple MPLS VPN scenario between PE4s:
[CE]-----[PE1]----[P]-----[PE(BORDER)]------[ISP1]
I give a brief description about the topology shown:
There is an MP-IBGP peering between PE1 and PE(BORDER).
PE1 has its CE interface associated to CLIENT VRF, and PE(BORDER) has all of
its interfaces associated to the global routing table.
PE(BORDER) also has the VRF created but none interface attached to the vrf,
so It can see the routes sourced from CE.
What I want is to give CE routing connectivity to ISP1 (internet), so the
data path a packet takes when it leaves CE router it follows PE1, then it
travels in the MPLS VPN to PE(BORDER) and then I leak that route from the
VPN to the global table using static routes, and then the packet succesfully
enters the ISP router, so at this point its working OK.
For the return packet I cant make the packet who comes from an interface of
the global table to enter the VRF TABLE (vpn) and travels via the VPN to
PE1.
I saw two examples found in cisco.com showing how to leak from VRF TO global
and from global to VRF, and in both cases it uses static routes pointing to
an outbound interface and a next hop, but my scenario is different to them
in that PE(BORDER) router has all of its interfaces attached to the global
routing table, and If I create a static route, to what outbound interface do
I point to? if all of its interfaces belong to the global routing table.
Please If any have an idea how to let it work?
Thanks.
