Routing Policy to Match Incoming RD

[dchockal1]

On CISCO ASR 9K routers

Can i have routing Policy to match the Incoming RD, and export the Routes based on the Incoming RD's. Basically I do not want to export certain routes to certain Incoming RD ( Router Distinguishers )

Though I could have Same Import RT and export  RT in those RD.

Example

RD 10.0.0.1:64                             ( I would Like ASR to Export Routes to this RD  )

        iRT  65201:64

        eRT 65201:64 

RD 90.0.0.1:64                              ( I would Like the ASR not to export the Routes to this RD )

        iRT  65201:64

        eRT 65201:64 

Is it Possible! And can i have some configuration examples as references

Hi,

RDs are not to be used for importing routes into VRFs –you can use the RTs for that purpose.

If you’re trying to import specific VRF routes but only those originated from a specific neighbour, you need to combine route-originator-ID with RT in your import policy match criteria.
