Configuring BGP4 neighbors
maxas-limit in num |disable specifies that the router discard routes that exceed a maximum AS
path length received in UPDATE messages. You can specify a value from 0 – 300. The default value
is 300. The disable keyword is used to stop a neighbor from inheriting the configuration from the
peer-group or global and to the use system default value.
maximum-prefix num specifies the maximum number of IP network prefixes (routes) that can be
learned from the specified neighbor or, if configured at peer group level, per neighbor in the peer
group. You can specify a value from 0 to 4294967295. The default is 0 (unlimited).
• The num value is the maximum number. The range is 0 – 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 maximum-prefix
configuration for the neighbor. The software also generates a Syslog message.
next-hop-self specifies that the device should list itself as the next hop in updates sent to the
specified neighbor. This option is disabled by default.
password string specifies an MD5 password for securing sessions between the device and its
neighbor. You can enter a string up to 80 characters long. The string can contain any alphanumeric
characters and spaces if the words in the password are placed inside quotes.
The system creates an MD5 hash of the password and use it for securing sessions between the
device and its neighbors. To display the configuration, the system uses a 2-way encoding scheme to
be able to retrieve the original password that was entered.
By default, password is encrypted. If you want password to be in clear text, insert a 0 between
password and string.
Brocade(config-bgp)# neighbor 10.157.22.26 password 0 marmalade
The system adds an encryption code followed by the encrypted text of the original password. For
example, the following portion of the code has the encrypted code “2”.
password 2 $IUA2PWc9LW9VIW9zVQ=="
One of the following may be displayed:
• 0 = the password is not encrypted and is in clear text
• 1 = the password uses proprietary simple cryptographic 2-way algorithm (only for Brocade
NetIron CES devices)
• 2 = the password uses proprietary base64 cryptographic 2-way algorithm (only for Brocade
NetIron XMR and Brocade MLX series devices)
peer-group group-name assigns the neighbor to the specified peer group.
prefix-list string in | out specifies an IP prefix list. You can use IP prefix lists to control routes to and
from the neighbor. IP prefix lists are an alternative method to AS-path filters. The in | out keywords
specify whether the list is applied on updates received from the neighbor or sent to the neighbor.
The filters can use the same prefix list or different prefix lists. To configure an IP prefix list, refer to
“Defining and applying IP prefix lists” on page 80.
remote-as as-number specifies the AS in which the remote neighbor resides. The as-number has
no default value. The range is 1 – 4294967295.
