Configuring BGP4 neighbors

• 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.
Virtual ADX(config-bgp-router)# neighbor 10.157.22.26 password 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.
• 2 = the password uses proprietary base64 cryptographic 2-way algorithm.
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 250.
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.
remove-private-as configures the device to remove private AS numbers from update messages the
device sends to this neighbor. The device will remove AS numbers 64512 – 65535 (the well-known
BGP4 private AS numbers) from the AS-path attribute in update messages the device sends to the
neighbor. This option is disabled by default.
route-map in | out map-name specifies a route map the device will apply to updates sent to or
received from the specified neighbor. The in | out keywords specify whether the list is applied on
updates received from the neighbor or sent to the neighbor.
NOTE
The route map must already be configured. Refer to “ “Defining route maps” on page 252.
send-community enables sending the community attribute in updates to the specified neighbor. By
default, the device does not send the community attribute.
