Re: about Area Splitting

["Li, Ke Qin (Peter)" <[e-mail]>]

Hi,

Thank you for your reply.

Let's still use the notations in that draft. In my understanding, when a
packet destined to y reaches a, a will discard the packet, and reply an ICMP
Destination Unreachable message. But this will not change the routing table
of c. C will keep sending packets to a.

What does "reject route" mean? And what does "coincide with computed
intra-area routes" mean? Do you mean that because m is not equal to x, a
reject route corresponding to m-x will be installed?

Thank you.
