• Use the no version to restore the default values on all neighbors—30 seconds for the
keepalive timer and 90 seconds for the hold-time timer.
• See timers bgp.
Automatic Summarization of Routes
By default, all routes redistributed into BGP from an IGP are automatically summarized
to their natural network masks.
auto-summary
• Use to reenable automatic summarization of routes redistributed into BGP.
• Automatic summarization is enabled by default. However, creating an address family
for a VRF automatically disables automatic summarization for that address family.
• This command takes effect immediately.
• Use the no version to disable automatic summarization of redistributed routes.
• See auto-summary.
Administrative Shutdown
You can administratively shut down particular BGP neighbors or peer groups without
removing their configuration from BGP by using the neighbor shutdown command.
You can also administratively shut down BGP globally by using the bgp shutdown
command.
bgp shutdown
• Use to shut down BGP globally.
• This command takes effect immediately.
• Example
host1(config-router)#bgp shutdown
• Use the no version to reenable BGP.
• See bgp shutdown.
neighbor shutdown
• Use to shut down a neighbor or peer group without removing their configuration.
• This command takes effect immediately.
• Use the no version to reenable a neighbor or peer group that was previously shut down.
Use the default version to remove the explicit configuration from the peer or peer group
and reestablish inheritance of the feature configuration.
• See neighbor shutdown.
