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.
