RA lifetime = 0 means: don't install this router as a > default router. YEs, it means to not install rhis router now as a default router, but maybe do it later. It is a matter of local configuration, but an Ethernet subnet might have several routers with lifetime==0 and one router with lifetime non-zero (the default router). All these routers would rather have the same reachable time 10seconds. The reachable time would depend on the kind of link layer technology, which is only one. Host1 Host2 ...
