142 ● filter-policy import 3Com Router 5000 Family and Router 6000 Family
Command Reference
Description In some cases, it may be required that only the routing information meeting some
conditions can be received. Then, the filter-policy command can be used to set
the filtering conditions for the routing information to be advertised. Only the routing
information passed the filtration can be received.
Since OSPF is a dynamic routing protocol based on link state, its routing information
hides in the link state, this command cannot filter the advertised/received routing
information in link state. There is more limitation when using this command in OSPF
than using it in distance vector routing protocol.
This command is valid for this process only if multiple OSPF processes are enabled.
