Hi,
I have network consists of 2 computers(say A and B) and a router.
When I use rtsol in A, I can get the global scope ipv6 address and the default gateway properly.
But when I send fake router advertisement messages from B, A accepts advertisements and makes fake address as default gateway. Ä°s this the expected behaviour?
What is the procedure for selecting default router?
thanks in advance...
