Parameters
number: Specifies the maximum number of active routes. In VPN instance view, the value range is 1
to 262144. In IPv4 VPN view, the value range is 1 to 1048576. In IPv6 VPN view, the value range is
1 to 262144.
warn-threshold: Specifies a warning threshold in the range of 1 to 100 in percentage. When the
percentage of the existing active routes to the maximum active routes exceeds the threshold, the
system gives a log message but still allows new active routes. If active routes in the VPN instance
reach the maximum, no more active routes are added.
simply-alert: Specifies that when active routes exceed the maximum number, the system still
accepts active routes but generates a log message.
Usage guidelines
Limiting the maximum number of active routes for a VPN instance can prevent a PE from learning
too many routes.
A limit configured in VPN instance view applies to both the IPv4 VPN and the IPv6 VPN. A limit
configured in IPv4 VPN view applies only to the IPv4 VPN. A limit configured in IPv6 VPN view
applies only to the IPv6 VPN.
If you have specified limits in both IPv4 VPN view and VPN instance view, IPv4 VPN uses the limit
specified in IPv4 VPN view.
If you have specified limits in both IPv6 VPN view and VPN instance view, IPv6 VPN uses the limit
specified in IPv6 VPN view.
Examples
# Specify that VPN instance vpn1 supports a maximum of 1000 active routes. When active routes
exceed this limit, the device can receive new active routes but generates a log message.
<Sysname> system-view
[Sysname] ip vpn-instance vpn1
[Sysname-vpn-instance-vpn1] route-distinguisher 100:1
[Sysname-vpn-instance-vpn1] routing-table limit 1000 simply-alert
# Specify that the IPv4 VPN vpn2 supports a maximum of 1000 active routes. When active routes
exceed this limit, the device can receive new active routes but generates a log message.
<Sysname> system-view
[Sysname] ip vpn-instance vpn2
[Sysname-vpn-instance-vpn2] route-distinguisher 100:2
[Sysname-vpn-instance-vpn2] address-family ipv4
[Sysname-vpn-ipv4-vpn2] routing-table limit 1000 simply-alert
# Specify that the IPv6 VPN vpn3 supports a maximum of 1000 active routes. When active routes
exceed this limit, the device can receive new active routes but generates a log message.
