rfc2328 states that when the cost of a virtual link changes, a new router-LSA should be originated for the backbone area.
The calculating result of 16.3(choosing another forwarding path different to virtual link path) will lead to new router-LSA generation in backbone area? This new chosen path can be regarded as virtual-link cost change?If no,I feel only some ABR(related to this transit area) or some other non-backbone areas attached to these ABRs can get the optimal path(via new-generated summary LSA).But for some internal routers in backbone area may not be able to forward traffic by best path because they get none of new router-lsa notification. Pls correct me and thanks in advance.
