When you are studying for the BSCI examination on the way to earning your CCNP accreditation, you have surely got to learn the use of BGP attributes. These capabilities permit you to manipulate the path or paths that BGP will use to achieve a given destination when numerous paths to that destination exist. In this free BGP tutorial, we're likely to have a look at-the NEXT_HOP feature. Perhaps you are considering "hey, how difficult can this attribute be?" It's not very complicated at all, but this being Cisco, there's got to be at least one unusual detail about it, right? The NEXT_HOP attribute is simple enough - this attribute indicates the next-hop IP address that needs to be taken to reach a destination. Within the following instance, R1 is a heart modem and R2 and R3 are spokes. All three routers are in BGP AS 100, with R1 having a relationship 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 feature on R1 is the IP on R3 that's used in the peer relationship, 172.12.123.3. If you think you know any thing, you will likely claim to explore about go here for more info. The issue using the attribute is available 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 attribute set to 172.12.123.3. Be taught supplementary info on our affiliated site by browsing to backlink indexer. The value is maintained, when a BGP speaker advertises a route to iBGP friends that has been initially learned from an eBGP expert. Here, all three routers are in AS 100. Visiting linklicious pro account possibly provides lessons you might give to your mother. What will the attribute be set to when R1 advertises the approach to its iBGP neighbor R2? R2#show ip bgp < no production > There will be no capability for the route on R2, since the route will not appear on R2. Automatically, a BGP speaker will not advertise a to iBGP neighbors if the route was first learned from another iBGP neighbor. To research more, consider having a glance at linklicious integration. Fortunately for all of us, there are numerous ways around this principle. The most typical is the usage of route reflectors, and we'll look at RRs in the next free BGP article..
