Parameters
ip ip-address: Specifies the IPv4 address to be protected. The ip-address argument cannot be all 1s or 0s.
ipv6 ipv6-address: Specifies the IPv6 address to be protected. The ipv6-address argument cannot be a
multicast address or all 0s.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the protected IP address
belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. Do not specify
this option if the protected IP address is on the public network.
