Routing-Table Limit - H3C S5820V2 Mce Command Reference

If the route tag carried in a Type-5 or Type-7 LSA received by an MCE is the same as the locally
configured route tag, the MCE neglects the LSA in route calculation to avoid routing loops.
Examples
# Set the route tag to 100 for OSPF process 100.
<Sysname> system-view
[Sysname] ospf 100
[Sysname-ospf-100] route-tag 100

routing-table limit

Use routing-table limit to set the maximum number of routes in a VPN instance.
Use undo routing-table limit to restore the default.
Syntax
routing-table limit number { warn-threshold | simply-alert }
undo routing-table limit
Default
No limit is set to the route number for a VPN instance.
Views
VPN instance view, IPv4 VPN view, IPv6 VPN view
Predefined user roles
network-admin
Parameters
number: Specifies the maximum number of routes. The value range is 1 to 8192 in VPN instance view
and IPv6 VPN view, and is 1 to 16384 in IPv4 VPN view.
warn-threshold: Specifies a warning threshold, in the range of 1 to 100 in percentages. When the
percentage of the number of existing routes to the maximum number of routes exceeds the specified
threshold, the system gives an alarm message but still permits new routes. If the number of routes in the
VPN instance reaches the maximum, no more routes are added.
simply-alert: Specifies that when the maximum route number is reached, the system still accepts routes
but generates a syslog message.
Description
This command prevents the MCE from learning excessive routes.
If you execute this command multiple times, the most recent configuration takes effect.
The setting configured in VPN instance view applies to both the IPv4 VPN and IPv6 VPN. The setting
configured in IPv4 VPN view applies only to the IPv4 VPN. The setting configured in IPv6 VPN view
applies only to the IPv6 VPN.
The setting configured in IPv4 VPN view or IPv6 VPN view takes precedence over that configured in VPN
instance view. If you configure a limit in both IPv4 VPN view (or IPv6 VPN view) and VPN instance view,
the IPv4 VPN (IPv6 VPN) uses the limit configured in IPv4 VPN view (IPv6 VPN view).
