Hey Cheong,
You might be confusing the ORIGIN attribute with Administrative Distance.
The "i" to the far left indicates that the route was learned from an IBGP
neighbor, which sets the AD to 200. The "i" to the far right indicates that
the route was originally learned from an IGP. The longest match rule and AD
are deciding factors that come even before the BGP selection process, so in
this case, the difference in AD will make the EBGP route more favorable.
If you do a show ip route, you'll see the AD for the route is 20.
Sincerely,
Fred
