Figure 23. Multi-Exit Discriminators Origin The origin indicates the origin of the prefix, or how the prefix came into BGP. There are three origin codes: IGP, EGP, INCOMPLETE. Origin Type IGP Description Indicates the prefix originated from information learned through an interior gateway protocol. EGP INCOMPLETE Indicates the prefix originated from information learned from an EGP protocol, which NGP replaced. Indicates that the prefix originated from an unknown source. Generally, an IGP indicator means that the route was derived inside the originating AS. EGP generally means that a route was learned from an external gateway protocol. An INCOMPLETE origin code generally results from aggregation, redistribution, or other indirect ways of installing routes into BGP. 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 Dell#show ip bgp BGP table version is 0, local router ID is 10.101.15.13 Status codes: s suppressed, d damped, h history, * valid, > best Path source: I - internal, a - aggregate, c - confed-external, r redistributed, n - network Origin codes: i - IGP, e - EGP, ? - incomplete Network *> 7.0.0.0/29 *> 7.0.0.0/30 *> 9.2.0.0/16 Next Hop 10.114.8.33 10.114.8.33 10.114.8.33 Metric 0 0 10 LocPrf 0 0 0 Weight 18508 18508 18508 Path ? ? 701 i Border Gateway Protocol IPv4 (BGPv4) 187
