15 AppleTalk IGRP303 Vermont#show appletalk globals AppleTalk global information Internet is compatible with older, AT Phase1,routers. There are 3 routes in the internet. There are 3 zones defined. Logging of significant appletalk events is disabled. ZIP resends queries every 10 seconds. RTMP updates are sent every 10 seconds. RTMP entries are considered BAD after 20 seconds. RTMP entries are discarded after 60 seconds. AARP probe retransmit count: 10, interval: 200 msec. AARP request retransmit count: 5, interval: 1000 msec. DDP datagrams will be checksunmmed. RTMP datagrams will be strictly checked. RTMP routes may not be propagated without zones. Routes will be distributed between routing protocols. Routing between local devices on an interface will not be p e r f o r m e d. IPTalk uses the udp base port of 768 (Default). EIGRP router id is: 101 EIGRP maximum active time is 3 minutes. Alternate node address format will not be displayed. Access control of any networks of a zone hides the zone.
