When youre learning for the BSCI assessment on the method to gaining your CCNP certification, you have surely got to learn the usage of BGP attributes. These capabilities permit you to manipulate the trail or paths that BGP will use to achieve certain destination when numerous paths to that destination exist. In this free BGP article, we are going to take a look in the NEXT_HOP feature. You may be considering "hey, how difficult can this capability be?" Its not so complicated at all, but this being Cisco, there is got to be at least one unusual aspect about it, right? The NEXT_HOP attribute is simple enough - this attribute indicates the next-hop INTERNET protocol address that needs to be taken to attain a spot. In the following example, R1 is a hub modem and R2 and R3 are spokes. All three routers are in BGP AS 100, with R1 having a relationship with both R2 and R3. Browse here at the link [http://www.indyarocks.com/blog/2092373/Learning-Photoshop-By-way-of-Video-Tutorials linklicious service] to read where to see this hypothesis. There is no BGP peering between R2 and R3. R3 is advertising the network 33.3.0.0 /24 via BGP, and the importance of the characteristic on R1 is the IP address on R3 thats utilized in the peer relationship, 172.12.123.3. The matter with the attribute will come in if the route is marketed to BGP peers. If R3 were in another AS from R1 and R2, R1 would then advertise the route to R2 with the attribute set to 172.12.123.3. Clicking [http://www.colourlovers.com/lover/proaccountkkz proaccountkkz : COLOURlovers] possibly provides tips you can tell your dad. When a BGP speaker advertises a path to iBGP friends which was initially learned from an eBGP peer, the value is stored. Here, all three routers are in AS 100. Whatll the characteristic be established to when R1 advertises the approach to its iBGP neighbor R2? R2#show ip address bgp  no production  There will be no next-hop attribute for the route on R2, since the route will not appear on R2. Automagically, a BGP speaker wont promote a to iBGP neighbors when the route was learned from another iBGP friend.
