12.1.17.28 Maximum-prefix Configuration
This command allows the configuration of a specified number of prefixes that a BGP
router is allowed to receive from a neighbor. When the
warning-only option is not used
and extra prefixes are received, the router ends the peering. A terminated peer stays
down until the
clear ip bgp command is used.
To control the number of prefixes that can be received from a neighbor, use the following
command.
Command Mode Description
neighbor { A.B.C.D | X:X::X:X |
WORD } maximum-prefix <1-
4294967295>
Router
AF
Sets up a BGP filter.
A.B.C.D: BGP neighbor IP address
X:X::X:X: BGP neighbor IPv6 address
WORD: BGP peer group
1-4294967295: maximum number of prefixes accepted
from this peer.
1-100: threshold value percent (%)
warning-only: only give a warning message when the
limit is exceeded.
out: filter outgoing advertised routes.
neighbor { A.B.C.D | X:X::X:X |
WORD } maximum-prefix <1-
4294967295> <1-100>
neighbor { A.B.C.D | X:X::X:X |
WORD } maximum-prefix <1-
4294967295> [<1-100>] warning-
only
no neighbor { A.B.C.D | X:X::X:X |
WORD } maximum-prefix <1-
4294967295> [<1-100>] [ warning-
only]
Disables this function.
12.1.17.29 The Number of Neighbor Configuration
To specify the BGP port number of a neighbor, use the following command.
Command Mode Description
neighbor { A.B.C.D | X:X::X:X |
WORD } port <0-65535>
Router
Specifies the BGP port number of a neighbor.
A.B.C.D: BGP neighbor IP address
X:X::X:X: BGP neighbor IPv6 address
WORD: BGP peer group or neighbor tag
0-65535: port number
no neighbor { A.B.C.D | X:X::X:X |
WORD } port <0-65535>
Deletes the configured port number.
12.1.17.30 Prefix-list Configuration
Filtering by prefix list matches the prefixes of routes with those listed in the prefix list. If
there is a match, the route is used. An empty prefix list permits all prefixes. If a given pre-
fix does not match any entries of a prefix list, the route is denied access. When multiple
entries of a prefix list match a prefix, the entry with the smallest sequence number is con-
sidered to be a real match.
The router begins the search at the top of the prefix list, with the sequence number 1.
Once a match or deny occurs, the router does not need to go through the rest of the pre-
fix list. For efficiency the most common matches or denies are listed at the top. The
