â—† A route metric must be used to resolve the problem of redistributing external
routes with incompatible metrics.
Example
Console(config-router)#redistribute static metric 10
Console(config-router)#
timers bgp This command sets the Keep Alive time used for maintaining connectivity, and the
Hold time to wait for Keep Alive or Update messages before declaring a neighbor
down. Use the no form to restore the default settings.
Syntax
timers bgp keepalive-time hold-time
no timers bgp
keepalive-time – The frequency at which the local router sends keep-alive
messages to its neighbors. (Range: 0-65535 seconds)
hold-time – The maximum interval after which a neighbor is declared dead
if a keep-alive or update message has not been received. (Range: 0-65535
seconds)
Command Mode
Router Configuration
Default Setting
Keep Alive time: 60 seconds
Hold time: 180 seconds
Command Usage
â—† Use this command to set global BGP timers used for monitoring connectivity to
neighboring routers. These timers will be applied to all neighbors unless the
neighbor timers command has been used to explicitly configure other timer
settings for a neighbor.
â—† When the minimum acceptable hold-time is configured with this command, a
remote peer session can be established only if the neighboring router is
advertising a hold-time equal to, or greater than, that configured on this device.
Example
Console(config-router)#timers bgp 60 200
Console(config-router)#
