In this chapter, a router refers to a general router or an Ethernet switch. To
improve readability, such a description of a router will not be given in the other
parts of the manual.
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-label, if-match mpls-label and if-match
