R21xx-HP FlexFabric 11900 MPLS Command Reference

113
An external route tag is not transferred in any BGP extended community attribute. It is only locally
significant and takes effect only on the PEs that receive BGP routes and generate OSPF Type 5 or 7 LSAs.
You can configure the same external route tag for different OSPF processes.
Examples
# In OSPF process 100, set the external route tag for redistributed VPN routes to 100.
<Sysname> system-view
[Sysname] ospf 100
[Sysname-ospf-100] route-tag 100

routing-table limit number { warn-threshold | simply-alert }
undo routing-table limit
Default
No route limit is set for a VPN instance.
Views
VPN instance view, IPv4 VPN view, IPv6 VPN view
Predefined user roles

Parameters
number: Specifies the maximum number of routes. The value range is 1 to 65536 in VPN instance view
and IPv6 VPN view, and is 1 to 524288 in IPv4 VPN view.
warn-threshold: Specifies a warning threshold in the range of 1 to 100 in percentage. 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 allows new routes. If routes in the VPN instance
reach the maximum, no more routes are added.
simply-alert: Specifies that when routes exceed the maximum number, the system still accepts routes but
generates a system log message.
Usage guidelines
A limit configured in VPN instance view applies to both the IPv4 VPN and the IPv6 VPN.
A limit configured in IPv4 VPN view or IPv6 VPN view applies to only the IPv4 VPN or the IPv6 VPN.
IPv4/IPv6 VPN prefers the limit configured in IPv4/IPv6 VPN view over the limit configured in VPN
instance view.
