do not have a VPN route tag set. The LSAs are assumed to be from a disjoint backbone

area.

You can change the configuration of the PE router’s routing instance to cause the PE

router to act as a non-ABR by including the disable statement at the [edit

routing-instances routing-instance-name protocols ospf domain-id] hierarchy level. You

make this configuration change to the hub PE router that receives the LSAs from the

hub CE router.

By making this configuration change, the PE router’s routing instance acts as a non-ABR.

The PE router then considers the LSAs arriving from the hub CE router as if they were

coming from a contiguous nonbackbone area.

Configuring RIP Between the PE and CE Routers

For a Layer 3 VPN, you can configure RIP on the PE router to learn the routes of the CE

router or to propagate the routes of the PE router to the CE router. RIP routes learned

from neighbors configured at any [edit routing-instances] hierarchy level are added to

the routing instance’s inet table (instance_name.inet.0).

To configure RIP as the routing protocol between the PE and the CE router, include the

rip statement:

rip {

group group-name {

export policy-names;

neighbor interface-name;

}

You can include this statement at the following hierarchy levels:

•

[edit routing-instances routing-instance-name protocols]

•

[edit logical-systems logical-system-name routing-instances routing-instance-name

protocols]

NOTE: The [edit logical-systems] hierarchy level is not applicable in ACX

Series routers.

By default, RIP does not advertise the routes it receives. To advertise routes from a PE

router to a CE router, you need to configure an export policy on the PE router for RIP. For

information about how to define policies for RIP, see Example: Applying Policies to RIP

Routes Imported from Neighbors.

To specify an export policy for RIP, include the export statement:

export [ policy-names ];

You can include this statement for RIP at the following hierarchy levels:

•

[edit routing-instances routing-instance-name protocols rip group group-name]
