Configuring BGP4
The <ip-addr> parameter specifies the IP address of the neighbor.
USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Click on the plus sign next to Configure in the tree view to expand the list of configuration options.
3. Click on the plus sign next to BGP in the tree view to expand the list of BGP option links.
4. Click on the Neighbor
link to display the BGP Neighbor panel.
NOTE: If the device already has neighbors, a table listing the neighbors is displayed. Click the Modify
button to the right of the row describing the neighbor to change its configuration, or click the Add Neighbor
link
to display the BGP Neighbor configuration panel.
5. Enter or modify parameters as needed. For detailed information, see “Adding BGP4 Neighbors” on page 10-
14.
6. Select the Enable radio button next to Shutdown.
7. Click the Add button (if you are adding a new neighbor) or the Modify button (if you are modifying a neighbor
that is already configured) to apply the changes to the device’s running-config file.
8. Select the Save
link at the bottom of the dialog, then select Yes when prompted to save the configuration
change to the startup-config file on the device’s flash memory.
Optional Configuration Tasks
The following sections describe how to perform optional BGP4 configuration tasks.
Changing the Keep Alive Time and Hold Time
The Keep Alive Time specifies how frequently the routing switch will send KEEPALIVE messages to its BGP4
neighbors. The Hold Time specifies how long the routing switch will wait for a KEEPALIVE or UPDATE message
from a neighbor before concluding that the neighbor is dead. When the routing switch concludes that a BGP4
neighbor is dead, the routing switch ends the BGP4 session and closes the TCP connection to the neighbor.
The default Keep Alive time is 60 seconds. The default Hold Time is 180 seconds. To change the timers, use
either of the following methods.
NOTE: Generally, you should set the Hold Time to three times the value of the Keep Alive Time.
NOTE: You can override the global Keep Alive Time and Hold Time on individual neighbors. See “Adding BGP4
Neighbors” on page 10-14.
USING THE CLI
To change the Keep Alive Time to 30 and Hold Time to 90, enter the following command:
HP9300(config-bgp-router)# timers keep-alive 30 hold-time 90
Syntax: timers keep-alive <num> hold-time <num>
For each keyword, <num> indicates the number of seconds. The Keep Alive Time can be 0 – 65535. The Hold
Time can be 0 or 3 – 65535 (1 and 2 are not allowed). If you set the Hold Time to 0, the routing switch waits
indefinitely for messages from a neighbor without concluding that the neighbor is dead.
USING THE WEB MANAGEMENT INTERFACE
