Basic configuration tasks
25
messages from a neighbor without concluding that the neighbor is dead. The defaults for these
parameters are the currently configured global Keep Alive Time and Hold Time. For more
information about these parameters, refer to “Changing the Keep Alive Time and Hold Time” on
page 767.
unsuppress-map <map-name> removes route dampening from a neighbor routes when those
routes have been dampened due to aggregation. Refer to “Removing route dampening from a
neighbor routes suppressed due to aggregation” on page 812.
update-source <ip-addr> | ethernet <portnum> | loopback <num> | ve <num> configures the
router to communicate with the neighbor through the specified interface. There is no default.
weight <num> specifies a weight the Layer 3 Switch will add to routes received from the specified
neighbor. BGP4 prefers larger weights over smaller weights. The default weight is 0.
Encryption of BGP4 MD5 authentication keys
When you configure a BGP4 neighbor or neighbor peer group, you can specify an MD5
authentication string for authenticating packets exchanged with the neighbor or peer group of
neighbors.
For added security, the software encrypts display of the authentication string by default. The
software also provides an optional parameter to disable encryption of the authentication string, on
an individual neighbor or peer group basis. By default, the MD5 authentication strings are
displayed in encrypted format in the output of the following commands:
• show running-config (or write terminal)
• show configuration
• show ip bgp config
When encryption of the authentication string is enabled, the string is encrypted in the CLI
regardless of the access level you are using.
If you display the running-config after reloading, the BGP4 commands that specify an
authentication string show the string in encrypted form.
In addition, when you save the configuration to the startup-config file, the file contains the new
BGP4 command syntax and encrypted passwords or strings.
NOTE
Dell recommends that you save a copy of the startup-config file for each switch you plan to upgrade.
Encryption example
The following commands configure a BGP4 neighbor and a peer group, and specify MD5
authentication strings (passwords) for authenticating packets exchanged with the neighbor or peer
group.
Here is how the commands appear when you display the BGP4 configuration commands.
