HP MSR2000/3000/4000 Router Series MPLS Command Reference

185
If the external route tag in a Type 5 or 7 LSA received by a PE is the same as the locally configured
external route tag, the PE ignores the LSA in route calculation to avoid routing loops.
HP recommends configuring the same external route tag for PEs in the same area.
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

Parameters
number: Specifies the maximum number of routes.
The following matrix shows the value ranges and default values for the number argument:
Item MSR2000 MSR3000 MSR4000
Value range 1 to 50000 1 to 100000 1 to 100000
Default value 100000 100000 100000
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.
