IP Routing Policy 
Configuration 
Commands
In some situations, it may be required that only some routing information meeting 
a certain condition be received. In this case, you can define a Filter-policy to filter 
advertised routing information so that only the routing information having passed 
the filtration can be received.
For the details about the apply mpls-labelif-match mpls-label and if-match 
vpn-target
 commands, refer to the 08-MPLS command module in the 3Com 
Switch 8800 Family Series Routing Switches Command Manual.
