Parameter
keepalive-interval: Set the interval time value for keepalive time. The range is 1 to
65535. By default, its value is 60 seconds.
holdtime-interval: Set the interval time value for hold time. The range is 3 to 65535. By
default, its value is 180 seconds.
Description

Use undo timer command to restore the default value of the Keep-alive and
Hold-time of the timer.

5.1.64 undo synchronization Syntax

BGP view
Parameter
None
Description
Use the undo synchronization command to cancel the synchronization of BGP and
IGP.
By default, BGP does not synchronize with IGP.
If the local BGP is not set synchronous with the IGP and the next hop of the learned
BGP route is reachable, the local BGP will add this BGP route into its routing table
immediately after it learns the route, rather than waiting till the IGP also learns the
route.
This command means BGP does not synchronize with IGP in current system. You
need not configure it for Switch 7750 Series Ethernet Switches don’t support
synchronization of BGP and IGP at present.
