i have cisco router to wan connection [only wan interface card], with my internal lan being 10.10.0.x, router being 10.10.0.1, now i need additional router to connect to adjacent building [with high speed etehrent lan] having their lan on 10.20.0.x is it possible to somehow attach additional router [for ex 10.10.0.2] with net interface to connect my lan with this adjacent building? i have read somewhere that there is some inter-router discovery protocol, and that my default router [wan] may discover and redirect traffic to this additional router, in case that subnet is required? of course, this my router 10.10.0.1 should remain as default gateway
thnx
