Configuring BGP4 neighbors
26
If you want to override the summary-only parameter and allow a specific route to be advertised to a
neighbor, enter commands such as the following.
The ip prefix-list command configures an IP prefix list for network 209.1.44.0/24, which is the
route you want to unsuppress. The next two commands configure a route map that uses the prefix
list as input. The neighbor command enables the device to advertise the routes specified in the
route map to neighbor 10.1.0.2. The clear command performs a soft reset of the session with the
neighbor so that the device can advertise the unsuppressed route.
Syntax: [no] neighbor <ip-addr> | <peer-group-name> unsuppress-map <map-name>
The following command verifies that the route has been unsuppressed.
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.
In addition, when you save the configuration to the startup configuration file, the file contains the
new BGP4 command syntax and encrypted passwords or strings.
NOTE
Brocade recommends that you save a copy of the startup configuration file for each device you plan
to upgrade.
