Locally injected routed is better than iBGP / eBGP learned. What is locally injected routed ? Is it the network specified by command network under BGP process ?

What is the difference between Origin "i" and Neighbor Type "i" ? Are they both refer to neighbor type ?

Thx

Locally injected route is a route that is advertised by router itself (either directly connected network or network learned via IGP (RIP, OSPF, EIGRP, IS-IS)). Local routes are given a weight of 32768 by default.
Left i (neighbor type) - marks iBGP neighbor
Right i (origin) - marks that network was advertised in BGP via network command (network that is directly connected or learned via IGP)

"Locally injected route is a route that is advertised by router itself". Does it exclude internal BGP route that is marked in right i (origin) ?

It excludes i (origin). Locally advertised routes can have value of ? if those are redistributed.
