When you are studying for the BSCI examination on the way to earning your CCNP certification, you have got to master the usage of BGP attributes. This dazzling go there essay has varied engaging suggestions for how to provide for it. These features allow you to adjust the road or paths that BGP use to achieve certain destination when multiple paths to that destination occur. Within this free BGP tutorial, we are planning to take a look at the NEXT_HOP attribute. Maybe you are considering hey, how complicated can this capability be? It is not so difficult at all, but this being Cisco, theres 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 should be taken to attain a destination. Within the following illustration, R1 is a hub switch and R3 and R2 are spokes.

All three routers are in BGP AS 100, with R1 having a connection with both R3 and R2. Theres no BGP peering between R3 and R2. R3 is advertising the community 33.3.0.0 /24 via BGP, and the importance of the credit on R1 is the IP address on R3 that is used in the peer relationship, 172.12.123.3. The issue with the credit will come in once the route is marketed to BGP peers. If R3 were in a different AS from R1 and R2, R1 would then advertise the route to R2 with the attribute set to 172.12.123.3. When a BGP speaker advertises a path to iBGP peers that was actually learned from an eBGP expert, the value is maintained. Here, all three routers are in AS 100. Whatll the next-hop characteristic be set to when R1 advertises the path to its iBGP friend R2? R2#show ip bgp < no output There will be no next-hop feature for the route on R2, since the route will not appear on R2. By default, a BGP speaker will not advertise a to iBGP neighbors when the route was first learned from another iBGP neighbor. Luckily for us, there are many ways around this concept. The most frequent is the use of route reflectors, and well look at RRs in another free BGP tutorial..
