Hi,

In section 13.3 of your draft, it states:

"Note that R1 and R2 will install a discard route for the configured summary
range. If the destination is not found in the attached area the packet is
discarded following the discard route entry in the routing table."

What does "discard route" mean?

"Note that the cost of on-demand TA should be set to maximum cost LSInfinity
(16-bit value 0xFFFF)."

Why the cost should be set to LSInfinity? When the TA is established, what
is the metric of summarized route of area 1 advertised by R1 into backbone
area?

Thank you.

Keqin Li
