Description (partial)

The configuration of "address-family ipv4 flowspec vrf <>" is saved in the nvgen as "address-family vpnv4 flowspec vrf <>" and hence show running-configuration shows "address-family vpnv4 flowspec vrf <>". The functionality is not impacted for the flow-spec CEs.
1) The Reload will lose the configuration of "address-family ipv4 flowspec vrf <>" .
2) In case of dual RP the config sync would not sync if the box reloads/switchovers with saved configs.

When we configure BGP-FS in vrf the cli is changed in show running as below, so it will cause this cli unrecognized after reload

address-family ipv4 flowspec vrf vrf100            >>>>>>>>>>>>>>>>>>>>>>>>   This cli is changed
  neighbor remote-as 100
  neighbor activate
Error info after reload
address-family vpnv4 flowspec vrf vrf100
