[FROG] VTYSH and BGP options

Hi All, New install of FRR on a Debian box, doing BGP on a couple of interfaces in a VRF (netns based). All is good except most of the bgp neighbour options are missing in VTYSH (neighbor <peer> <option>). In particular the options for weight or as-prepent or as-path filtering are missing. Is there something obvious I'm missing? * Simon
