When you are learning for the BSCI exam on the method to getting your CCNP certification, you have surely got to master the usage of BGP attributes. These attributes allow you to adjust the road or paths that BGP uses to achieve certain destination when numerous paths to that destination occur. In this free BGP article, were going to take a look in the NEXT_HOP attribute. You might be thinking "hey, how difficult can this attribute be?" Its not very difficult at all, but this being Cisco, theres got to be at least one unusual detail about it, right? The NEXT_HOP attribute is straightforward enough - this attribute indicates the next-hop IP address that should be taken to reach a spot. Within the following illustration, R1 is a center switch and R3 and R2 are spokes. All three routers come in BGP AS 100, with R1 having a connection with both R3 and R2. We found out about privacy by searching newspapers. Linkilicious.Me contains new resources concerning the inner workings of this view. Theres no BGP peering between R3 and R2. R3 is advertising the community 33.3.0.0 /24 via BGP, and the value of the next-hop credit on R1 is the IP on R3 that is used in the peer relationship, 172.12.123.3. The matter using the next-hop feature will come in once the route is marketed to BGP peers. If R3 were in a separate AS from R1 and R2, the route would be then advertised by R1 to R2 using the next-hop attribute set to 172.12.123.3. Whenever a BGP speaker advertises an approach to iBGP colleagues that was originally learned from an eBGP fellow, the value is kept. Here, all three routers are in AS 100.

What will the characteristic be established to when R1 advertises the path to its iBGP friend R2? R2#show ip address bgp no production There will be no next-hop capability for the route on R2, because the route will not appear on R2. Automagically, a BGP speaker will not advertise a to iBGP neighbors when the route was initially learned from another iBGP friend. Fortunately for us, there are many ways around this concept.
