Changing the BGP4 next-hop update timer

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. Refer to
"Configuring BGP4 neighbors"
To change the Keep Alive Time to 30 and Hold Time to 90, enter the following command.
BigIron RX(config-bgp)# 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 router waits indefinitely for messages from a neighbor without concluding that the
neighbor is dead.
Changing the BGP4 next-hop update timer
By default, the device updates its BGP4 next-hop tables and affected BGP4 routes five seconds
after IGP route changes. You can change the update timer to a value from 1 – 30 seconds.
To change the BGP4 update timer value, enter a command such as the following at the BGP
configuration level of the CLI.
BigIron RX(config-bgp)# update-time 15
This command changes the update timer to 15 seconds.
Syntax: [no] update-time <secs>
The <secs> parameter specifies the number of seconds and can be from 1 – 30. The default is 5.

Changing the router ID

The OSPF and BGP4 protocols use router IDs to identify the routers that are running the protocols.
A router ID is a valid, unique IP address and sometimes is an IP address configured on the router.
The router ID cannot be an IP address in use by another device.
By default, the router ID on a device is one of the following:
•
•
780
If the router has loopback interfaces, the default router ID is the IP address configured on the
lowest numbered loopback interface configured on the device. For example, if you configure
loopback interfaces 1, 2, and 3 as follows, the default router ID is 9.9.9.9/24:
•
Loopback interface 1, 9.9.9.9/24
•
Loopback interface 2, 4.4.4.4/24
•
Loopback interface 3, 1.1.1.1/24
If the device does not have any loopback interfaces, the default router ID is the lowest
numbered IP interface address configured on the device.
