Configuring a BGP4 peer group

•
NOTE
If you want the software to assume that the value you enter is the clear-text form, and to encrypt
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.
Displaying the authentication string
If you want to display the authentication string, enter the following commands:
BigIron RX(config)# enable password-display
BigIron RX(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. Display of the string 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.
Configuring a BGP4 peer group
A peer group is a set of BGP4 neighbors that share common parameters. Peer groups provide the
following benefits:
•

You can perform the following tasks on a peer-group basis:

1 – Assumes that the authentication string you enter is the encrypted form, and decrypts the
value before using it.
Simplified neighbor configuration – You can configure a set of neighbor parameters and then
apply them to multiple neighbors. You do not need to individually configure the common
parameters individually on each neighbor.
Flash memory conservation – Using peer groups instead of individually configuring all the
parameters for each neighbor requires fewer configuration commands in the startup
configuration file.
Reset neighbor sessions
Perform soft-outbound resets (the device updates outgoing route information to neighbors but
does not entirely reset the sessions with those neighbors)
Clear BGP message statistics
Clear error buffers
