Routing-Table Limit - HP FlexNetwork 3600 v2 Series Command Reference Manual

An RD is used to create the routing and forwarding table of a VPN. By prefixing an RD to an IPv4
prefix, you make the VPN IPv4 prefix unique globally.
NOTE:
• No RD is configured by default; you must configure an RD for each VPN instance.
• A VPN instance takes effect only after you configure an RD for it.
• Once you configure an RD for a VPN, you cannot remove the association.
• You cannot change an RD directly; you can only delete the VPN instance, re-create the VPN
instance, and then reconfigure a new RD.
Examples
# Configure the RD of VPN instance vpn1.
<Sysname> system-view
[Sysname] ip vpn-instance vpn1
[Sysname-vpn-instance-vpn1] route-distinguisher 22:1

routing-table limit

Syntax
routing-table limit number { warn-threshold | simply-alert }
undo routing-table limit
View
VPN instance view, IPv4 VPN view
Default level
2: System level
Parameters
number: Maximum number of routes for the VPN instance to support. The maximum number ranges
from 1 to 6144 in VPN instance view and from 1 to 12288 in IPv4 VPN view.
warn-threshold: Specifies a threshold for warning, in the range of 1 to 100, in percentages. When the
percentage of the number of existing routes to the maximum number of routes supported exceeds
the specified threshold, the system gives an alarm message but still allows new routes. If the number
of routes in the VPN instance reaches the maximum supported, no more routes are added.
simply-alert: Specifies that when the number of routes exceeds the maximum number of routes
supported, the system still accepts routes but generates a system log (Syslog) message.
Description
Use routing-table limit to limit the maximum number of routes in a VPN instance, preventing too
many routes from being accepted by a PE.
Use undo routing-table limit to restore the default.
By default, no limit is configured.
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 to only the IPv4 VPN.
A limit configured in IPv4 VPN view takes precedence over that configured in VPN instance view. If
you configure a limit in both IPv4 VPN view and VPN instance view, the IPv4 VPN uses the limit
configured in IPv4 VPN view.
