CCNA Notes : cont..
54. IP RIP based networks send the complete routing table
during update. The default update interval is 30 seconds. IGRP
update packet is sent every 90 seconds by default.
55. For IGRP routing, you need to provide the AS (Autonomous
System) number in the command. Routers need AS number to exchange
routing information. Routers belonging to same AS exchange routing
information. OSPF, and IGRP use AS numbers.
56. CDP stands for Cisco Discovery Protocol. This
protocol is proprietary of Cisco. CDP runs SNAP (Sub network Access
Protocol) at the Data Link Layer. Two Cisco devices running two
different Network layer protocol can still communicate and learn
about each other.
