BGP is http://edition.cnn.com/search/?text=토토사이트 The most advanced subject areas you’ll examine when pursuing your CCNP, Otherwise essentially the most advanced. I know from individual knowledge that when I was earning my CCNP, BGP is the topic that gave me probably the most issues in the beginning. Another thing I preserve reminding these days’s CCNP candidates about, although, is usually that no Cisco technology is impossible to know if you simply crack it down and understand the fundamentals before you start attempting to grasp the greater elaborate configurations.
BGP attributes are just one such topic. You’ve obtained nicely-regarded necessary, very well-recognized discretionary, transitive, and non-transitive. Then you’ve received Just about every person BGP attribute to recall, and also the order by which BGP considers characteristics, and what characteristics even are… in addition to a good deal far more! As with every other Cisco subject, we really need to stroll in advance of we can easily operate. Enable’s Look into what characteristics are and what they do in BGP.
BGP attributes are very similar to what metrics are to OSPF, RIP, IGRP, and EIGRP. You gained’t see them detailed inside a routing table, but attributes are what BGP considers When picking the very best route to the desired destination when a number of legitimate (loop-totally free) paths exist.
When BGP has to choose concerning such paths, You can find an get wherein BGP considers The trail attributes. For achievement about the CCNP exams, you have to know this order. BGP seems to be at path attributes In this particular buy:
Maximum weight (Cisco-proprietary BGP worth)
Maximum community preference (LOCAL_PREF)
Choose regionally originated route.
Shortest AS_PATH is favored.
Select route with cheapest origin code. Inside paths are chosen around external paths, and external paths are desired about paths by having an origin of “incomplete”.
Cheapest multi-exit discriminator (MED)
Exterior BGP routes favored above Inner BGP routes.
If no external route, pick out path with cheapest IGP Expense to the next-hop router for iBGP.
Select most up-to-date route.
Pick most affordable BGP RID (Router ID).
If you don’t understand what these values are, or how they’re configured, don’t panic! Another a number of aspects of this BGP tutorial will describe all of it. So shell out some time learning this buy, and in part II of this cost-free BGP tutorial, we’ll have a look at 안전놀이터 each of those values intimately. Continue to keep finding out!
