When youre studying for the BSCI exam on the method to getting your CCNP certification, youve surely got to master the use of BGP attributes. These features enable you to adjust the trail or paths that BGP will use to reach certain destination when multiple paths to that destination occur. Within this free BGP article, were likely to have a look at the NEXT_HOP characteristic. Perhaps you are thinking "hey, how complicated can this credit be?" Its not very difficult at all, but this being Cisco, there is got to be at least one unusual aspect about it, right? The NEXT_HOP attribute is easy enough - this attribute indicates the next-hop INTERNET protocol address that needs to be taken to reach a destination. Within the following instance, R1 is a hub modem and R3 and R2 are spokes. Clicking tell us what you think possibly provides cautions you can give to your pastor. All three routers are in BGP AS 100, with R1 having a relationship with both R3 and R2. There is no BGP peering between R3 and R2. R3 is advertising the community 33.3.0.0 /24 via BGP, and the importance of the feature on R1 is the IP on R3 that is found in the peer relationship, 172.12.123.3. The problem using the next-hop attribute comes in if the route is marketed to BGP peers. If R3 were in a separate AS from R1 and R2, R1 could then advertise the course to R2 with the attribute set to 172.12.123.3. When a BGP speaker advertises an approach to iBGP peers that has been initially learned from an eBGP fellow, the value is stored. Here, all three routers come in AS 100. What will the next-hop feature be established to when R1 advertises the path to its iBGP neighbor R2? R2#show internet protocol address bgp no production There will be no next-hop credit for the route on R2, because the route wont appear on R2. Be taught extra information on a partner paper - Click this link linklicious.me tutorial. By default, a route will not be advertised by a BGP speaker to iBGP neighbors if the route was first learned from another iBGP neighbor. Fortuitously 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 training..
