Regarding Origin Code in BGP

Hi Experts,

I have a query regarding Origin code in BGP. Below is my topology:

R1<----FR link ----> R2

R2 advertise's the network 2.2.0.2/24 to R1 via BGP. The output for the same
on R1 is as follows:

r1#show ip bgp | in 2.2.0.2
*> 2.2.2.0/24 10.1.12.2 0 0 200 *i*

Now my doubt is the " *i* " on the right hand side is the origin code which
is IGP, but since i am advertising it via BGP why am i seeing it as IGP??
