Cisco CCNP / BSCI Tutorial: The BGP Attribute NEXT_HOP

When you are studying for the BSCI examination on the solution to getting your CCNP certification, you have surely got to master the usage of BGP attributes. These attributes enable you to change the path or paths that BGP will use to reach a given destination when numerous paths to that destination occur. Within this free BGP training, we are likely to take a look at the NEXT_HOP feature. You may well be considering "hey, how complicated may this attribute be?" It's 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 straightforward enough - this attribute indicates the next-hop INTERNET protocol address that should be taken to achieve a destination. To study additional information, please consider checking out: guide to linklicious case study. Within the following example, R1 is a link hub and R2 and R3 are spokes. All three routers come in BGP AS 100, with R1 having a connection with both R3 and R2. There is no BGP peering between R2 and R3. R3 is advertising the network 33.3.0.0 /24 via BGP, and the value of the next-hop credit on R1 is the IP on R3 that's utilized in the peer relationship, 172.12.123.3. The matter using the feature comes in if the route is marketed to BGP peers. If R3 were in a different AS from R1 and R2, the route would be then advertised by R1 to R2 with the next-hop attribute set to 172.12.123.3. The next-hop value is stored, when a BGP speaker advertises an approach to iBGP peers which was initially learned from an eBGP expert. Here, all three routers come in AS 100. What'll the feature be established to when R1 advertises the route to its iBGP friend R2? R2#show ip bgp < no output > There will be no next-hop attribute for the route on R2, because the route will not look on R2. By default, a BGP speaker will not advertise a to iBGP neighbors when the route was first learned from another iBGP neighbor.

The most common is the utilization of route reflectors, and we'll look at RRs in another free BGP training..
