Usage guidelines
If you do not specify any parameter, the command clears IPv4 source guard binding entries on all
interfaces on the public network.
Examples
# Clear all IPv4 source guard binding entries on the public network.
<Sysname> reset ip source binding
# Clear IPv4 source guard binding entries with the source IPv4 address being 2.2.2.2.
<Sysname> reset ip source binding static ip-address 2.2.2.2
# Clear all dynamic IPv4 source guard binding entries in VPN 1.
<Sysname> reset ip source binding vpn-instance 1
# Clear all dynamic IPv4 source guard binding entries created by DHCP relay in VPN 1.
