BGP Question

Hi all,

I advertised 174.1.1.0/24 network in BGP on R1, when I see sh ip bgp
174.1.1.0 on R4 it mentions Origin IGP, can any one tell me why origin is
IGP when route is advertised and learned via BGP? Both R1 and R4 are in
same AS of BGP.

Rack1R4#sh ip bgp 174.1.1.0
BGP routing table entry for 174.1.1.0/24, version 17
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Not advertised to any peer
Local
174.1.145.1 from 174.1.145.1 (150.1.1.1)
Origin IGP, metric 0, localpref 100, valid, confed-internal, best

Regards,

Mohammad Zahid Saeed
