30 Basic configuration tasks indefinitely for 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 1004. unsuppress-map 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 1057. update-source | ethernet | loopback | ve configures the router to communicate with the neighbor through the specified interface. There is no default. weight 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. PowerConnect(config-bgp-router)#local-as 2 PowerConnect(config-bgp-router)#neighbor xyz peer-group PowerConnect(config-bgp-router)#neighbor xyz password abc PowerConnect(config-bgp-router)#neighbor 10.10.200.102 peer-group xyz PowerConnect(config-bgp-router)#neighbor 10.10.200.102 password test Here is how the commands appear when you display the BGP4 configuration commands. 998 PowerConnect B-Series FCX Configuration Guide 53-1002266-01
