Parameters
None
Usage guidelines
With this feature enabled and when a non-BGP router is responsible for forwarding packets in an AS,
IPv6 BGP speakers in the AS cannot advertise routing information to other ASs unless all routers in the AS
know the latest routing information.
Examples
# Enable the route synchronization between IPv6 BGP and IGP.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family
[Sysname-bgp-af-ipv6] synchronization
timer (IPv6 address family view)
Use timer to specify the IPv6 BGP keepalive interval and holdtime interval.
Use undo timer to restore the default.
Syntax
timer keepalive keepalive hold holdtime
undo timer
Default
The keepalive and holdtime intervals are 60 seconds and 180 seconds, respectively.
Views
IPv6 address family view
Default command 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.
Usage guidelines
The timers configured with the peer timer command are preferred to the timers configured with the timer
command.
If the holdtime interval is configured as 0, no keepalive message is sent to the peer, and the peer
connection never times 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.
