Ok, day 2 in the where is the documentation for series of posts. Today I was looking for the Cisco Documentation on First Hop Redundancy Protocols.

HSRP, VRRP, GLBP – It is actually under IP Application Services. So from the top

www.cisco.com / Support / Configure / Producst / Cisco IOS and NX-OS Software / Cisco IOS / 12.4 / 12.4 T / Configuration Guides / IP Application Services

And under there it is listed under First Hop Redundancy Protocols.

Direct link here http://www.cisco.com/en/US/docs/ios/ipapp/configuration/guide/12_4t/iap_12_4t_book.html

Enjoy!
