Figure 10. Three Internet-Provisioned Sites on an MPLS Network Provide Internet Access for
Remote Sites
The following configuration applies to Example 8:
Primary Site
In this example, the default route advertised with RIP by the external firewall (local prefix) is to be
preferred.
!
interface eth 0/1
ip address 192.168.1.1 255.255.255.0
no shutdown
!
This example represents a typical MPLS BGP configuration where there is only one PE
router that is an eBGP neighbor to the customer’s router. Much of the BGP community
configuration is done by the MPLS provider, leaving the customer with a much simpler
configuration for the desired failover application. A sample configuration that shows what
the configuration would look like if the MPLS cloud was a single AOS unit is provided at
the end of this example.
