Export map on MPLS VPN / VRF

[j.vanrooyen]

We have an MPLS VPN based network based on leased lines. One of the VPN's connects to a banking service , a number of the other VPN's would also like to make use of this service. I would like to export the specific route from the "Banking VPN" into the other VPN's but this route only. I have tried to apply an export map to the VRF but this does not seem to work , the only other way to control this would be to apply an import map to every one of the VRF's where I would like to import this route to but that does not seem to be the most effciennt way to do it.

What are the criteria for an export map to work ? I might be doing something incorrectly. Here is an example of the config I have done.

1) Created an ACL matching the ip of the route

ip access-list extended ABC

permit ip x.x.x.x 0.0.0.15 any

2) Created route-map to apply to VRF

route-map DEF permit 10

match ip address ABC

3) Applied the export map to the vrf

ip vrf XYZ

RD65000:999

export map DEF

route-target export 65000:999

When I do a show of the route-map I do not get any matches and a show vrf detail does indicate the export map to be applied. The destination addresses of the route is reachable from the VRF in question.

Any help would be appreciated.

Hi,

The operation of a export map is different from an import map. In an export map you do the following:

* You tag the selected router (trough ACL or prefix list), and add an additional route-target to it.

* In the other VPN's you should then import that new route target.

ip vrf test

export map TEST

RD 65000:1

route-target both 65000:1

ip vrf TEST2

RD 65000:2

route-target both 65000:2

route-target import 65000:999

ip access-list ACL1 extended

permit X.X.X.X Y.Y.Y.Y.Y

route-map TEST

match ip address ACL1

set extcommunity RT 65000:999 additive

Hope this helps,
