Hello, everyone.

Now, I am reading the RFC2328, but I found one question, can your help me?

In Section 11.1:
....
Before the lookup begins, "discard" routing table entries should
be inserted into the routing table for each of the router's active area
address ranges (see Section 3.5). (An area range is considered "active"
if the range contains one or more networks reachable by intra-area
paths.) The destination of a "discard" entry is the set of addresses
described by its associated active area address range, and the path type
of each "discard" entry is set to "inter-area".[10]
...

I don't know what is the "discard route", why need this step?

Thanks.

Jina.
