BGP Best Path Selection

On Cisco's guide to the BGP bestpath selection algorithm (here: http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094431.shtml) -- about halfway down the page under the "Example" section, the following output is shown:

Comparing path 1 with path 2:
Both paths have reachable next hops
Both paths have a WEIGHT of 0
Both paths have a LOCAL_PREF of 100
Both paths are learned
Both paths have AS_PATH length 1
Both paths are of origin IGP
The paths have different neighbor AS's so ignoring MED
Both paths are internal
(no distinction is made between confed-internal and confed-external)
Both paths have an IGP metric to the NEXT_HOP of 20645
Path 2 is better than path 1 because it has a lower Router-ID.

Comparing path 2 with path 3:
Both paths have reachable next hops
Both paths have a WEIGHT of 0
Both paths have a LOCAL_PREF of 100
Both paths are learned
Both paths have AS_PATH length 1
Both paths are of origin IGP
Both paths have the same neighbor AS, 65089, so comparing MED.
Both paths have a MED of 0
Both paths are confed-external
Both paths have an IGP metric to the NEXT_HOP of 20645
Path 2 is better than path 3 because it has a lower Router-ID.


 What is the actual debug that shows this process?
