When a BGP instance with a manually assigned VPN label is deleted, the label is not released from the Zebra label registry. As a result, reapplying a configuration with the same manual label leads to VPN prefix export failures. For example, with the following configuration: > router bgp 65000 vrf BLUE > address-family ipv4 unicast > label vpn export <int> Release zebra label registry on unconfiguration. Fixes: d162d5f ("bgpd: fix hardset l3vpn label available in mpls pool") Signed-off-by: Louis Scalbert <louis.scalbert@6wind.com>
