TAILIEUCHUNG - Packet communicating in an IP World 30

Tech Tips Top His List The First Quarter 2004 issue of Packet® was excellent with its coverage of security, IOS®, high availability, etc. I read with particular interest of the AutoSecure feature in Cisco IOS Software Release Mainline. But all the information is very helpful to us because we’re installing a Cisco infrastructure at our facilities. I am familiar with Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) but was not familiar with Gateway Load Balancing Protocol (GLBP) until now. The article on GLBP written by Rick Williams, “High Availability for Campus Networks,” is especially useful to me. I probably will be able to use GLBP for my dual-connected remote sites to do load sharing. I also liked. | PACKET CISCO SYSTEMS USERS MAGAZINE Power over Ethernet Branch of the Future SECOND QUARTER 2004 Cisco Systems I packet Reprinted with permission from Packet magazine Volume 16 No. 2 copyright 2004 by Cisco Systems Inc.
