2) Those configured with the route-tag command are in the second place in terms of
priority level.
3) Those configure with the default tag command are of the lowest priority level.
If the route-tag included in the type-5/-7 LSA is identical with its existing tag, the LSA
received will be neglected in route calculation.
Caution:
To validate the configured route-tag, you must execute the reset ospf command.
Related command: import-route and default.
Example
# Configure route-tag 100 to OSPF process 100.
[3Com -ospf-100] route-tag 100
OSPF: Process 100's route tag has been changed
OSPF: Reload or use 'reset ospf' command for this to take effect

View
MBGP VPN-instance view
Parameter
threshold-value: Threshold of the maximum route count. When the number of routes
reaches this threshold, no route can be added. It is in the range 1 to 1000.
warn-threshold: Warn threshold percentage. When the number of routes exceeds the
threshold of the maximum route count times the warn threshold, alarm is generated.
The warn threshold is in the range 1 to 100.
syslog-alert: Allows a route to be added when the number of routes reaches the
threshold of the maximum route count. In this case, a SYSLOG error message is sent.
Description
Use the routing-table limit command to limit the route maximum in a vpn-instance, to
avoid too many routes in the ingress interface of the PE router.
