GroupStudy.com CCIE-LAB List – Best of 1/7/2008 – Why People Fail The Lab + TFTP Opens Random Ports + OSPF LSAs That Don’t Get In The Routing Table

Like passive mode FTP, TFTP can open random ports. TFTP can be matched for QoS purposes using NBAR.
There are times when you’ll see LSAs in the OSPF database that don’t make it in the routing table. This document explains why that can happen, often because the advertised next-hop is unreachable due to mismatched OSPF network types.
