Parameters
source-ip-address: Specifies an IPv4 address for the blacklist entry. Packets sourced from this
address will be dropped.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the blacklist
belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. Do not
specify this option if the blacklist is on the public network.
ds-lite-peer ds-lite-peer-address: Specifies the IPv6 address of the B4 element of the DS-Lite tunnel
that transmits packets from the blacklisted IPv4 address.
timeout minutes: Specifies the aging time in minutes for the blacklist entry, in the range of 1 to 1000.
If you do not specify this option, the blacklist entry never ages out. You must delete it manually.
Usage guidelines
The undo blacklist ip command deletes only manually added IPv4 blacklist entries. To delete
dynamically added IPv4 blacklist entries, use the reset blacklist ip command.
A blacklist entry with an aging time is not saved to the configuration file and cannot survive a reboot.
You can use the display blacklist ip command to display all effective IPv4 blacklist entries.
