Timer (Bgp/Bgp-Vpn Instance View) - HP 6125G Command Reference Manual

Parameters
None
Description
Use synchronization to enable the synchronization between the BGP and IGP routes.
Use undo synchronization to disable the synchronization.
The feature is disabled by default.
With this feature enabled and when a non-BGP router is responsible for forwarding packets in an AS,
BGP speakers in the AS cannot advertise routing information to other ASs unless all routers in the AS
know the latest routing information.
When a BGP router receives an IBGP route, it checks only whether the next hop is reachable by default.
If the synchronization is enabled, the IBGP route is synchronized and advertised to EBGP peers only
when the route is also advertised by IGP. Otherwise, the IBGP route cannot be advertised to EBGP peers.
Examples
# Enable the synchronization between BGP and IGP routes.

timer (BGP/BGP-VPN instance view)

Syntax
timer keepalive keepalive hold holdtime
undo timer
View
BGP view, BGP-VPN instance view
Default level
2: System level
Parameters
keepalive: Keepalive interval in seconds, ranging from 0 to 21845.
holdtime: Holdtime interval in seconds, whose value is 0 or in the range of 3 to 65535.
Description
Use timer to configure the BGP keepalive interval and holdtime interval.
Use undo timer to restore the default.
By default, the BGP keepalive interval and the holdtime interval are 60 seconds and 180 seconds.
The timers configured with the peer timer command are preferred to the timers configured with this
command.
If the holdtime interval is configured as 0, no keepalive message will be sent to the peer, and the peer
connection will never time out. If the keepalive interval is configured as 0 and the negotiated hold time
is not 0, one third of the hold time is taken as the interval for sending keepalive messages.
