filter-list in | out <num,num,...> specifies an AS-path filter list or a list of AS-path ACLs. The in | out
keyword specifies whether the list is applied on updates received from the neighbor or sent to the
neighbor. If you specify in or out, The <num,num,...> parameter specifies the list of AS-path filters.
The router applies the filters in the order in which you list them and stops applying the filters in the
AS-path filter list when a match is found. The weight <num> parameter specifies a weight that the
Layer 3 Switch applies to routes received from the neighbor that match the AS-path filter or ACL.
You can specify a number from 0 through 65535.
Alternatively, you can specify filter-list <ACL-num> in | out | weight to use an AS-path ACL instead of
an AS-path filter list. In this case, <ACL-num> is an AS-path ACL.
NOTE
By default, if an AS-path does not match any of the filters or ACLs, the Layer 3 Switch denies the
route. To change the default behavior, configure the last filter or ACL as “permit any any”.
NOTE
The AS-path filter or ACL must already be configured. Refer to “Filtering AS-paths” on page 1035.
maximum-prefix <num> specifies the maximum number of IP network prefixes (routes) that can be
learned from the specified neighbor or peer group. You can specify a value from 0 through
4294967295. The default is 0 (unlimited):
The <num> parameter specifies the maximum number. You can specify a value from 0 through
4294967295. The default is 0 (unlimited).
The <threshold> parameter specifies the percentage of the value you specified for the
maximum-prefix <num>, at which you want the software to generate a Syslog message. You
can specify a value from 1 (one percent) to 100 (100 percent). The default is 100.
The teardown parameter tears down the neighbor session if the maximum-prefix limit is
exceeded. The session remains shutdown until you clear the prefixes using the clear ip bgp
neighbor all or clear ip bgp neighbor <ip-addr> command, or change the neighbor
maximum-prefix configuration. The software also generates a Syslog message.
next-hop-self specifies that the router should list itself as the next hop in updates sent to the
specified neighbor. This option is disabled by default.
The nlri multicast | unicast | multicast unicast parameter specifies whether the neighbor is a
multicast neighbor or a unicast neighbor. Optionally, you also can specify unicast if you want the
Layer 3 Switch to exchange unicast (BGP4) routes as well as multicast routes with the neighbor.
The default is unicast only.
password [0 | 1] <string> specifies an MD5 password for securing sessions between the Layer 3
Switch and the neighbor. You can enter a string up to 80 characters long. The string can contain
any alphanumeric characters, but the first character cannot be a number. If the password contains
a number, do not enter a space following the number.
The 0 | 1 parameter is the encryption option, which you can omit (the default) or which can be one
of the following:
0 – Disables encryption for the authentication string you specify with the command. The
password or string is shown as clear text in the output of commands that display neighbor or
peer group configuration information.
1 – Assumes that the authentication string you enter is the encrypted form, and decrypts the
value before using it.
For more information, refer to “Encryption of BGP4 MD5 authentication keys” on page 998.
