i have situation where i'm receiving a /26 subnet via CPE router and i only want to advertise /29 subnet to EBGP. is there any way to do that? i can't advertise whole /26 as it breaks other customer. Note: /29 prefix does not live on the box so i can't advertise them directly. Any help would be highly appreciated.

Hi Jay, Some boxes can support routes deaggregation with conditional routes injection. Also, you could use ODL BGP's programmable RIB to inject such "modified" (more specific) prefixes to the network (i.e. eBGP peer).
