In the Dell Networking OS, these origin codes appear as shown in the following example. The question mark
(?) indicates an origin code of INCOMPLETE (shown in bold). The lower case letter (i) indicates an origin code
of IGP (shown in bold).
Example of Viewing Origin Codes

AS Path
The AS path is the list of all ASs that all the prefixes listed in the update have passed through.
The local AS number is added by the BGP speaker when advertising to a eBGP neighbor.
The AS path is shown in the following example. The origin attribute is shown following the AS path
information (shown in bold).

Next Hop
The next hop is the IP address used to reach the advertising router.
For EBGP neighbors, the next-hop address is the IP address of the connection between the neighbors. For
IBGP, the EBGP next-hop address is carried into the local AS. A next hop attribute is set when a BGP speaker
advertises itself to another BGP speaker outside its local AS and when advertising routes within an AS. The
next hop attribute also serves as a way to direct traffic to another BGP speaker, rather than waiting for a
speaker to advertise.
