Advancement
In order to address the issues of address space and other factors, Cisco created EIGRP (Enhanced Interior Gateway Routing Protocol). EIGRP adds support for VLSM (variable length subnet mask) and adds the Diffusing Update Algorithm (DUAL) in order to improve routing and provide a loopless environment. EIGRP has completely replaced IGRP, making IGRP an obsolete routing protocol. In Cisco IOS versions 12.3 and greater, IGRP is completely unsupported. In the new Cisco CCNA curriculum (version 4), IGRP is mentioned only briefly, as an "obsolete protocol".

Famous quotes containing the word advancement:
“Woman—with a capital letter—should by now have ceased to be a specialty. There should be no more need of “movements” on her behalf, and agitations for her advancement and development ... than for the abolition of negro slavery in the United States.”
—Marion Harland (1830–1922)
“Racism is when you have laws set up, systematically put in a way to keep people from advancing, to stop the advancement of a people. Black people have never had the power to enforce racism, and so this is something that white America is going to have to work out themselves. If they decide they want to stop it, curtail it, or to do the right thing ... then it will be done, but not until then.”
—Spike Lee (b. 1956)
“If we could produce one or two more Madame Curies, that would accomplish far more for the advancement of women than any amount of agitation, argument and legislation.”
—Virginia Crocheron Gildersleeve (1877–1965)
