While eBGP routes are prefered over iBGP routes, LocalPref takes
preference, so the route through R2 should be prefered by R1, not the
route through the eBGP peer.

Subject: Help with Local Preference
R1 and R2 are IBGP peers within the same AS, and they are both EBGP
peering with other AS.
A route-map for local preference was created on R2 for a destination X.
R1 learned a route to X via his EBGP peer, and it was assigned a local
preference 100. R2 also learned a route to X via his EBGP peer, and it
was assigned a higher local-pref 200 because of using the route-map. R2
passed the route with higher local-pref to R1.
From the point of view of R1, the best path to X is through his EBGP
peer or R2??
The router will prefer its external route or its internal route with
higher local preference??
Thanks for all the feedback ...
