Specifying A List Of Networks To Advertise - Dell PowerConnect B-RX Configuration Manual

The <ip-addr> parameter specifies the IP address of the neighbor.
The <peer-group-name> parameter specifies the peer group name.
NOTE
You must add the peer group before you can add neighbors to it.
Administratively shutting down a session with a BGP4 neighbor
You can prevent the device from starting a BGP4 session with a neighbor by administratively
shutting down the neighbor. This option is very useful for situations in which you want to configure
parameters for a neighbor but are not ready to use the neighbor. You can shut the neighbor down
as soon as you have added it the device, configure the neighbor parameters, then allow the device
to reestablish a session with the neighbor by removing the shutdown option from the neighbor.
When you apply the new option to shut down a neighbor, the option takes place immediately and
remains in effect until you remove the option. If you save the configuration to the startup
configuration file, the shutdown option remains in effect even after a software reload.
NOTE
The software also contains an option to end the session with a BGP4 neighbor and thus clear the
routes learned from the neighbor. Unlike this clear option, the option for shutting down the neighbor
can be saved in the startup configuration file and thus can prevent the device from establishing a
BGP4 session with the neighbor even after reloading the software.
NOTE
If you notice that a particular BGP4 neighbor never establishes a session with the device, check the
device's running configuration and startup configuration files to see whether the configuration
contains a command that is shutting down the neighbor. The neighbor may have been shut down
previously by an administrator.
To shut down a BGP4 neighbor, enter commands such as the following.
BigIron RX(config)# router bgp
BigIron RX(config-bgp)# neighbor 209.157.22.26 shutdown
BigIron RX(config-bgp)# write memory
Syntax: [no] neighbor <ip-addr> shutdown
The <ip-addr> parameter specifies the IP address of the neighbor.

Specifying a list of networks to advertise

By default, the router sends BGP4 routes only for the networks you either identify with the network
command or are redistributed into BGP from OSPF, ISIS, RIP, or connected routes.
NOTE
The exact route must exist in the IP route table before the device can create a local BGP route.
To configure the device to advertise network 209.157.22.0/24, enter the following command.
BigIron RX(config-bgp)# network 209.157.22.0 255.255.255.0
Syntax: network <ip-addr> <ip-mask> [route-map <map-name>] | [weight <num>] | [backdoor]
