Setting The Local As Number; Changing The Maximum Number Of Shared Bgp4 Paths - Dell PowerConnect B-RX Configuration Manual

The router waits for the Hold Time to expire before ending the connection to a directly-attached
BGP4 neighbor that dies.
For directly attached neighbors, the router immediately senses loss of a connection to the neighbor
from a change of state of the port or interface that connects the router to its neighbor. For directly
attached EBGP neighbors, the router can use this information to immediately close the BGP4
session and TCP connection to locally attached neighbors that die.
NOTE
The fast external fallover feature applies only to directly attached EBGP neighbors. The feature does
not apply to IBGP neighbors.
To enable fast external fallover, enter the following command.
BigIron RX(config-bgp)# fast-external-fallover
To disable fast external fallover again, enter the following command.
BigIron RX(config-bgp)# no fast-external-fallover
Syntax: [no] fast-external-fallover

Setting the local AS number

The local AS number identifies the AS the Brocade BGP4 router is in.
To set the local AS number, enter commands such as the following.
BigIron RX(config)# router bgp
BGP4: Please configure 'local-as' parameter in order to enable BGP4.
BigIron RX(config-bgp)# local-as 10
BigIron RX(config-bgp)# write memory
Syntax: [no] local-as <num>
The <num> parameter specifies the local AS number 1 – 65535. There is no default. AS numbers
64512 – 65535 are the well-known private BGP4 AS numbers and are not advertised to the
Internet community.

Changing the maximum number of shared BGP4 paths

When IP load sharing is enabled, BGP4 can balance traffic to a specific destination across up to
eight equal paths. You can set the maximum number of paths to a value from 1 – 8. The default is
1.
NOTE
The maximum number of BGP4 load sharing paths cannot be greater than the maximum number of
IP load sharing paths. To increase the maximum number of IP load sharing paths, use the ip load
sharing <num> command at the global CONFIG level of the CLI or use the # of Paths field next to
Load Sharing on the IP configuration panel of the Web management interface.
To change the maximum number of shared paths, enter commands such as the following.
BigIron RX(config)# router bgp
BigIron RX(config-bgp)# maximum-paths 4
BigIron RX(config-bgp)# write memory
