[c-nsp] VRF import default route from global routing table on the Same PE with internet and NNI to a provider

[TOMAZ, Mariano]

Have you considered the command "import ipv4 unicast" under the vrf
definition?
Check the following link:

Hope this helps.

Asunto: [c-nsp] VRF import default route from global routing table on
the Same PE with internet and NNI to a provider

I am trying to figure a way to import a default route from the global
routing table into a customer's VRF to provide internet access. This
customer's site is on another's provider network that we interconnect
with using a NNI and option b.

Our PE has MPLS L3 VPNs, NNI Link to a provider, and full internet
routes.

So here is the layout

Cust---Provider1---NNI_LINK----PE----Internet


So I see three ways of doing this.

1. Configuring a Internet gateway and attach it off the PE using vlans
 
Cust-Provider--NNI_LINK---PE---dot1qtrunk--InternetGateway--PE--Internet


        PE G0/0 Vlan10
                vrf CUST
                ip addr 10.1.1.2/30

        Ineternetgateway G0/0 vlan 10
                No vrf
                Ip addr 10.1.1.1/30

        Internetgateway G0/1
                Ip addr 2.2.2.2/30

        PE G0/1
                IP addr 2.2.2.1/30

2. I know the global commands won't work because that requires a
dedicated "Internet Gateway Router" and the route back to the customer's
CE won't work because of the NNI Link and the customer is not directly
attached to our PE

3. Loopback Cable on the PE one side in the vrf and the other in the
internet routing table.
        G0/0.10  MPLS VRF Interface
                Vlan 10
                Vrf cust
                Ip addr 10.1.1.2/30

        G0/1.10  Internet Routing
                Vlan 10
                Ip addr 10.1.1.1/30

If there is another way to do this let me know.


Thanks in advance.

Erik
