i've been studying switch almost exclusively since february... i am still in no rush to test; the means is always more important than the end... in that time i've been mostly avoiding route except for how it pertains to switch, and i'm getting weary of it...
routing has always been my strength; my first cisco experience was bringing up a 3640 with an atm connection to replace an existing t1 a long time ago...
in the last two weeks i've bought pdf copies of routing tcpip by jeff doyle, and ccnp route by wendell odom... it's good to get back to wendell as i haven't been a big fan of the hucaby switch ocg... both ebooks on sale at cisco for a greatly discounted price through what was originally ebook of the day, and is now ebook of the week... if you don't keep an eye on those bargains you are not helping yourselves...
so if you haven't noticed, i'm beginning to insinuate route into the posts... at this point there are roughly 2 hundred switch specific posts covering most of the syllabus... time to mix it up a little bit, and as always, the beginning never ends...
eigrp uses 3 basic mechanisms to add routes to its table...
neighbor discovery eigrp sends hello messages in an effort to discover
potential neighbors
topology exchange when the neighborship comes up, full routing tables are
exchanged; thereafter partial updates are in order based on topology changes
route selection eigrp analyzes the topology table, and selects the lowest-cost
route to reach the target subnet
update messages are sent on 224.0.0.10 for multiple routers on the same subnet
network cisco ccna gns3 certification arteq
a network runs through it
