jardiance® (empagliflozin) familyIn this free BGP tutorial, we are planning to take a peek at the NEXT_HOP attribute. You may well be thinking "hey, how difficult may this feature be?" It's not so complex at all, but this being Cisco, there's got to be at least one unusual aspect about it, right?

The NEXT_HOP attribute is easy enough - this attribute indicates the next-hop IP address that needs to be taken to reach a spot. In the following illustration, R1 is a heart router and R3 and R2 are spokes. All three routers are in BGP AS 100, with R1 having a relationship with both R3 and R2. There's no BGP peering between R3 and R2. Be taught more on this related portfolio by clicking is linklicious worth the money.

R3 is advertising the community 33.3.0.0 /24 via BGP, and the value of the credit on R1 is the IP on R3 that is utilized in the peer relationship, 172.12.123.3.

The problem with the next-hop feature comes in when the route is marketed to BGP peers. If R3 were in another AS from R1 and R2, the route would be then advertised by R1 to R2 with the attribute set to 172.12.123.3. The next-hop value is kept, whenever a BGP speaker advertises a route to iBGP peers that was actually learned from an eBGP fellow.

Here, all three routers come in AS 100. What'll the next-hop credit be established to when R1 advertises the route to its iBGP neighbor R2?

R2#show ip address bgp

< no output >

There will be no credit for the route on R2, as the route won't look on R2. By default, a route won't be advertised by a BGP speaker to iBGP neighbors if the route was initially learned from another iBGP friend.

Fortunately for us, there are many ways around this principle. The most typical is using route reflectors, and we'll look at RRs in a future free BGP article..
