[Sysname-bgp-ipv4-vpn1] peer 1.1.1.1 substitute-as
peer timer (BGP/BGP-VPN instance view)
Use peer timer to configure the keepalive interval and holdtime for a peer or peer group.
Use undo peer timer to restore the default.
Syntax
peer { group-name | ip-address } timer keepalive keepalive hold holdtime
undo peer { group-name | ip-address } timer
Default
The keepalive and holdtime are 60s and 180s, respectively.
Views
BGP view, BGP-VPN instance view
Default command level
2: System level
Parameters
group-name: Specifies the name of a peer group, a sting of 1 to 47 characters.
ip-address: Specifies the IP address of a peer.
keepalive: Specifies the keepalive interval in seconds, in the range of 0 to 21845.
holdtime: Specifies the holdtime interval in seconds, whose value is 0 or in the range of 3 to 65535.
Usage guidelines
The timers configured with this command are preferred to the timers configured with the timer command.
If the holdtime 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.
If neither the holdtime nor the keepalive interval is configured as 0, the holdtime must be at least three
times the keepalive interval.
After this command is executed, the peer connection is closed at once, and a new connection to the peer
is negotiated using the configured hold time.
Examples
# In BGP view, configure the keepalive interval and holdtime for peer group test as 60s and 180s.
