Questions keep coming: what to believe and why? Brought to mind something I found on CCO once. The topic was the maximum network diameter of an EIGRP network. The following is a quote from CCO: IP Enhanced IGRP provides the following features: (snip) Increased network width. With IP RIP, the largest possible width of your network is 15 hops. When IP Enhanced IGRP is enabled, the largest possible width is 224 hops. Because the Enhanced IGRP metric is large enough to support thousands of hops, the only barrier to expanding the network is the transport layer hop counter. Cisco works around this problem by incrementing the transport control field only when an IP packet has traversed 15 routers and the next hop to the destination was learned via Enhanced IGRP. When a RIP route is being used as the next hop to the destination, the transport control field is incremented as usual. http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/ciprout e.htm#xtocid248438 watch the wrap the statement remains incredibly amusing, even after all this time. I continue to wonder exactly what field is being manipulated here. Just an idle thought, along with numbers of hosts per vlan and the difference between layer 3 switching and routing. Chuck One IOS to forward them all. One IOS to find them. One IOS to summarize them all And in the routing table bind them. -JRR Chambers- Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=8801&t=8801 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
