R211x-HP Flexfabric 11900 MPLS Command Reference

164
An external route tag can be configured by different commands and has different priorities. The
commands used to configure the external route tag (in the descending order of tag priority) are as
follows:
• import-route
• route-tag
• default tag
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
