On a HPE Aruba Networking 6300M switch someone had changed the outbound BGP policy, but apparently the platform did not trigger outbound BGP updates automatically in that case, so I was looking for a soft outbound reset functionality.
Tested with AOS-CX version FL.10.13.1090:
myarubaswitch# clear bgp vrf MY_VRF ipv4 unicast 10.10.10.10 soft out
Invalid input: out
myarubaswitch# clear bgp vrf MY_VRF ipv4 unicast * soft out
Invalid input: out
myarubaswitch# clear bgp vrf MY_VRF all 10.10.10.10 soft out
Invalid input: out
myarubaswitch# clear bgp vrf MY_VRF all * soft out
myarubaswitch#
Task finally completed.
Luckily, this has been improved in later versions, for example in FL.10.16.1030:
myarubaswitch# clear bgp vrf MY_VRF ipv4 unicast 10.10.10.10 soft ?
in Soft reconfig inbound update
out Soft reconfig outbound update
myarubaswitch# clear bgp vrf MY_VRF ipv4 unicast 10.10.10.10 soft out
myarubaswitch#
