In your previous mail you wrote:
While implement Host side of RA, I suddently noticed that my code
makes no difference for
RA with Router Lifetime = 600
and
RA with Prefix ::0/0, L=0, A=0, Lifetime = 600
Both create effectively a default route pointing to this router. Am I
doing something wrong?
=> perhaps, Prefix ::0/0 is an illegal prefix...
Suppose we had RA with
Router Lifetime = 600
Prefix X/48, L=0, A=0, Lifetime = 1200
The way 6.3.5 is written, seems to say that both ::0/0 and X/48 should
be removed.
=> you mix up router lifetime (which is in fact the lifetime as a default
router) and prefix lifetimes (which are the lifetimes of the prefix).
The router is removed from the default router list when *its* lifetime
is expired, this should have no effect on the prefix list.
The same question arises also, when router sends RA with Router
Lifetime=0.
=> this *only* means the router is not suitable as a default router,
nothing more.
