maximum-paths

Use this command to set the maximum number of routes the load
balance of OSPF protocol supports. Restore default with the no
form of this command.
Router configuration
maximum-paths <number>
no maximum-paths [<number>]
<number>
� This command is supported after the platform version 4.6.02.
�
Once a router has a complete link status database, it is ready
to create its routing table for forwarding data stream. The
default overhead metric is based on the bandwidth of network
medium. To calculate the minimum overhead arriving at the
destination, at most 8 route entries of overhead are saved in
the routing table for load balance. This can be configured by
the maximum-paths command.
� The router generally selects the path with the minimum metric
value. If multiple paths with the same maximum metric val-
ues appear at the same time, load balance will be enabled on
these paths. The maximum-paths command can be used to
support at most eight paths with the same metric value.
� This command takes effect immediately after the configuration,
and it is in time-sharing processing mode. There is no need to
manually interfere, but is needs to wait for a certain time.
This example sets the maximum number of routes load balance of
OSPF protocol supports as 4.

This command is configured on PE routers. Use this command to
