Imported routes point to the same interface and next hop as the original route. Shared

IP interfaces are not created.

Table 89 on page 430 lists additional characteristics of import and global import maps.

Table 89: Characteristics of Import and Global Import Maps

Global ImportImportCharacteristic

–YesDistributes routes from the global BGP VPN RIB local to the VR. This

RIB is often referred to as the core VPN RIB.

Yes–Distributes routes from the global BGP non-VPN RIB local to the

VR. This RIB is often referred to as the core non-VPN RIB or core RIB.

YesYesImports all types of routes (received routes, redistributed routes,

network routes, aggregate routes, and auto-summary routes).

YesYesImports both best and non-best routes. The best route selection

(including the decision to use or not use ECMP) is made in the VRF

after the routes are imported.

Characteristics of Export and Global Export Maps

Export maps and global export maps can export both labeled and unlabeled routes. If

you want to export only one or the other, you can use a match mpls-label command in

the export or global export route map.

Table 90 on page 430 lists additional characteristics of export and global export maps.

–YesDistributes routes to the global BGP VPN RIB local to the VR. This

RIB is often referred to as the core VPN RIB.

Yes–Distributes routes to the global BGP non-VPN RIB local to the VR.

This RIB is often referred to as the core non-VPN RIB or core RIB.

–YesExports all types of routes (received routes, redistributed routes,

network routes, aggregate routes, and auto-summary routes).

Yes–Exports only locally originated routes (all routes other than those

that have been received).

YesYesExports both best and non-best routes. The best route selection is

made again in the core after the export.

Subsequent Distribution of Routes

Routes that are imported from the global BGP non-VPN RIB (with a global import map)

into a VRF RIB are never exported again. Because these routes are not exported to the
