Usage Guidelines This command requires the LAN Enterprise Services license.
Examples This example shows how to enable an unencrypted key for a BGP neighbor:
switch# configure terminal
switch(config)# router bgp 101
switch(config-router)# neighbor 192.0.2.1 remote-as 1.2
switch(config-route-neighbor)# password 0 myauthkey
switch(config-route-neighbor)#
This example shows how to disable an unencrypted authentication key for a BGP neighbor:
switch# configure terminal
switch(config)# router bgp 101
switch(config-router)# neighbor 192.0.2.1 remote-as 1.2
switch(config-route-neighbor)# no password 0 myauthkey
switch(config-route-neighbor)#
auth-key (Optional) MD5 authentication key. You can enter an unencrypted (cleartext) key, or
one of these values followed by a space and the MD5 authentication key:
• 0—Specifies an unencrypted (cleartext) key
• 3—Specifies a 3-DES encrypted key
• 7—Specifies a Cisco Type 7 encrypted key
The key can be from 1 to 16 characters.
