Concept Guide
Setting the extended timer
To congure BGP idle hold time, use the following commands.
Timer values congured with the neighbor timers extended command override the timer values congured with the timers bgp
extended command.
The peer remains in idle state based on the congured idle-holdtime. The less the idle-holdtime, lesser the peer remains in idle
state.
NOTE: For the new idle-holdtime to take eect, you need to shutdown the respective peer manually using neighbor
shutdown command and enable the peer again.
• Congure idle-holdtime values for a BGP neighbor or peer group.
CONFIG-ROUTER-BGP mode
neighbors {ip-address | ipv6-address | peer-group-name} timers extended idle-holdtime
idle-holdtime: the range is from 1 to 32767. Time interval, in seconds, during which the peer remains in idle state. The default is 15
seconds.
• Congure idle-holdtime values for all BGP neighbors.
CONFIG-ROUTER-BGP mode
timers bgp extended idle holdtime
idle-holdtime: the range is from 1 to 32767. Time interval, in seconds, during which the peer remains in idle state. The default is 15
seconds
.
Enabling or disabling BGP neighbors
You can enable or disable all the congured BGP neighbors using the shutdown all command in ROUTER BGP mode.
To disable all the congured BGP neighbors:
1 Enter the router bgp mode using the following command:
CONFIGURATION Mode
router bgp as-number
2 In ROUTER BGP mode, enter the following command:
ROUTER BGP Mode
shutdown all
You can use the no shutdown all command in the ROUTER BGP mode to re-enable all the BGP interface.
You can also enable or disable BGP neighbors corresponding to the IPv4 unicast or multicast address families and the IPv6 unicast address
family.
To enable or disable BGP neighbors corresponding to the IPv4 unicast address families, use the following commands:
1 Enter the router bgp mode using the following command:
CONFIGURATION Mode
router bgp as-number
