In "show apple zone" if a zone shows up with a ":20" this represents a entered at the end of the zone name. Zone names must match between routers!

Zone names must match between routers So Marketing and Marketing 20 wouldn t agree. When you have a GRE tunnel established try to tunnel multiple protocols on it rather than running parallel tunnels Doing a no appletalk routing then appletalk routing re-initializes appletalk BUT it takes out and replaces all basic commands like RTMP but not commands related to eigrp or aurp. AURP uses UDP port 387. Make sure it s NOT filtered through an access-list AURP needs to be full mesh Won t router Notes Cable ranges go from 1-253. 0 254 and 255 reserv .
