Since the default behavior does not affect the BGP4 configuration itself but does encrypt display of the authentication string, the CLI
does not list the encryption options.
Syntax:
[no] neighbor
{
ip-addr
|
peer-group-name
}
password
string
The
ip-addr
|
peer-group-name
parameter indicates whether you are configuring an individual neighbor or a peer group. If you specify
the IP address of a neighbor, you are configuring that individual neighbor. If you specify a peer group name, you are configuring a peer
group.
If you want the software to assume that the value you enter is the clear-text form and to encrypt the display of that form, do not enter 0 or
1. Instead, omit the encryption option and allow the software to use the default behavior. If you specify encryption option 1, the software
assumes that you are entering the encrypted form of the password or authentication string. In this case, the software decrypts the
password or string you enter before using the value for authentication. If you accidentally enter option 1 followed by the clear-text version
of the password or string, authentication will fail because the value used by the software will not match the value you intended to use.
The
password
string
parameter specifies an MD5 authentication string to secure sessions between the device and the neighbor. You can
enter a string of up to 80 characters. The string can contain any alphanumeric characters, but must be placed inside quotes if it contains
a space.
The system creates an MD5 hash of the password and uses it to secure sessions between the device and the neighbors. To display the
configuration, the system uses a 2-way encoding scheme to retrieve the original password.
By default, password is encrypted. If you want the password to be in clear text, insert a 0 between
password
and
string.
device(config-bgp)# neighbor 10.157.22.26 password admin
Displaying the authentication string
To display the authentication string, enter the following commands.
device(config)# enable password-display
device(config)# show ip bgp neighbors
The
enable password-display
command enables display of the authentication string, but only in the output of the
show ip bgp
neighbors
command. String display is still encrypted in the startup configuration file and running configuration. Enter the command at
the global CONFIG level of the CLI.
NOTE
The command also displays SNMP community strings in clear text, in the output of the
show snmp server
command.
Displaying neighbor information
To display IPv6 unicast route summary information, enter the
show ip bgp ipv6 summary
command:
device(config-bgp)# show ip bgp ipv6 summary
