Filter Policies
Router Configuration Guide 563
The no form of this command deletes the specified prefix from the list.
Operational Notes:
To add set of different prefixes, execute the command with all unique prefixes. The prefixes are
allowed to overlap IPv6 address space.
An IPv6 prefix addition will be blocked, if resource exhaustion is detected anywhere in the system
because of filter policies that use this IPv6 address prefix list.
Default No prefixes are in the list by default
Parameters ipv6-prefix — An IPv6 address prefix written as hexadecimal numbers separated by colons with
host bits set to 0. One string of zeros can be omitted so 1010::700:0:217A is equivalent to
1010:0:0:0:0:700:0:217A
Values x:x:x:x:x:x:x:x (eight 16-bit pieces)
x:x:x:x:x:x:d.d.d.d
x: [0..FFFF]H
d: [0..255]D
prefix-length — Length of the entered IPv6 prefix.
Values 1 to 128
prefix
Syntax prefix ip-prefix/prefix-length
