Internet Access from an MPLS VPN Using a Global Route Table when multihomed

I have configured in the lab the example from "internet access from an MPLS VPN using a global routing table", Cisco document id 24508 which uses the static command:

ip route vrf customer1 0.0.0.0 0.0.0.0 192.168.67.1 global

I cannot find any method of providing internet access when multi-homed.

Previously the Cisco "MPLS and VPN architecture" book specifies the use of the command "ip vrf forwarding CustomerA fallback global" which does not specify the next-hop, this seems to be the answer to the problem but it does not exist in the IOS code.

Thanks in advance

Hi

If you use dual-homing with 2 PE and 1 CE and static routing, than you should do the mentioned static route configuration on both PE routers and static routing on CE with different AD.

Thanks for your response.

I am interested in the ability to setup redundant routing using different internet service providers for all customers.

Any info would be great.

just a cautionary note that this document has a small omission in the config for the PE2 router..

address-family ipv4 vrf customer1

no synchronization

network 22.22.22.0 mask 255.255.255.0

network 192.168.20.0 mask 255.255.255.252

The CE2/PE2 link wasnt advertised.

CE1 was able to ping CE2, but not vice-versa. CE2 was able to ping CE1 using the loopback 0 address as the source..
