@svnrnns Looking in the comments for any AIDA64 peeps. My first hello world was in this language.

iBGP advertises routes with the next hop attribute unchanged. Called next-hop-unchanged

[Mr_Iseijin @Mralien1112]

When eBGp peers send routes, it sets the next-hop attribute to itself. This is called next-hop-self.

[Mr_Iseijin @Mralien1112]

The Originator attribute in BGP. A client can check if it received its own route back by checking the originator attribute. Not the only way but it is a way.

[Mr_Iseijin @Mralien1112]

In BGP RR, a loop prevention mechanism for an RR is to prepend its Cluster-ID to a route sent to a client. If it sees its Cluster-ID back, it drops or ignores the route.

[Mr_Iseijin @Mralien1112]

An iBGP peer cannot advertise iBGP learner routes to another iBGP peers. RR is the exception
