By default, upon receiving an IPv6 IBGP route, the BGP router only checks whether the next hop is 

reachable before advertisement. If synchronization is enabled, the IBGP route can be advertised to 

EBGP peers only when the route is also advertised by the IGP.  

 

Currently, the system does not support synchronization. Therefore, the configuration of this command 

does not actually take effect.

keepalive: Keepalive interval in seconds, ranging from 1 to 21845. 

holdtime: Holdtime interval in seconds, ranging from 3 to 65535. 

Use the timer command to specify IPv6 BGP keepalive interval and holdtime interval. 

Use the undo timer command to restore the default. 

By default, the keepalive and holdtime intervals are 60s and 180s respectively. 

Note that:  

z 

Timer configured using the peer timer command is preferred to the timer configured using the 

timer command.  

z 

The holdtime interval must be at least three times the keepalive interval.  

z 

The configured timer applies to all the IPv6 BGP peers. It becomes valid only after the 

corresponding IPv6 BGP connections are reset.
