When you're learning for the BSCI examination on the method to getting your CCNP certification, you've surely got to learn the usage of BGP attributes. These features allow you to adjust the trail or paths that BGP will use to attain certain destination when numerous paths to that destination exist. In this free BGP article, we are going to take a peek at the NEXT_HOP attribute. You may be thinking "hey, how difficult could this feature be?" It's not so complicated at all, but this being Cisco, there's 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 should be taken to achieve a destination. In the following illustration, R1 is a heart hub and R2 and R3 are spokes. All three routers come in BGP AS 100, with R1 having a relationship with both R2 and R3. There's no BGP peering between R2 and R3. R3 is advertising the network 33.3.0.0 /24 via BGP, and the importance of the next-hop credit on R1 is the IP address on R3 that's utilized in the peer relationship, 172.12.123.3. The matter using the credit will come in if the route is marketed to BGP peers. In the event people wish to discover more about [http://wallinside.com/post-44862-report-promotion-tips-and-traps.html linklicious works], we know of millions of databases you should think about pursuing. If R3 were in a different AS from R1 and R2, the route would be then advertised by R1 to R2 using the attribute set to 172.12.123.3. Whenever a BGP speaker advertises an approach to iBGP peers which was initially learned from an eBGP expert, the value is maintained. Here, all three routers come in AS 100.

What will the next-hop attribute be set to when R1 advertises the route to its iBGP neighbor R2? R2#show ip bgp < no productivity > There will be no credit for the route on R2, since the route will not appear on R2. By default, a BGP speaker won't advertise a to iBGP neighbors if the route was learned from another iBGP friend. Fortunately for all of us, there are many ways around this principle. The most common is the use of route reflectors, and we'll look at RRs in a future free BGP article..
