neighbor maximum-prefix (IPv6 Address Family
Configuration)
In IPv6 address family configuration mode, the neighbor maximum-prefix
command specifies the maximum number of IPv6 prefixes that BGP will
accept from a given neighbor.
Syntax
neighbor { ip-address | ipv6-address [ interface interface-id ]} maximum-
prefix { maximum [threshold] [warning-only] | unlimited }
no neighbor { ip-address | ipv6-address [ interface interface-id ]} maximum-
prefix
• ip-address—The neighbor’s IP address.
• ipv6-address—The neighbor’s IPv6 address. If the neighbor’s IPv6 address
is a link local address, the local interface must also be specified.
• interface-id—If the neighbor’s IPv6 address is a link local address, the local
VLAN routing interface must also be specified.
• maximum—The maximum number of prefixes BGP will accept from this
neighbor. Range 0-4294967295. Values greater than the free space in the
route table are not enforced.
• threshold—The percentage of the maximum number of prefixes BGP
configured for this neighbor. When the number of prefixes received from
the neighbor exceeds this percentage of the maximum, BGP writes a log
message. The range is 1 to 100 percent. The default is 75%. Unless
warning-only is specified, BGP shuts down the adjacency when the
threshold is reached.
