Explanation:

EBP
1) Has lowest default admin distance:

The Default admin distances are
EBGP 20
IGP 100
IBGP 200
See: http://www.cisco.com/warp/public/105/admin_distance.pdf
2) Propagates routing updates to external neighbours

eBGP is used to send routing updates to external neighbours ————————————–
IBGP
1) Has the highest default admin distance:

The Default admin distances are
EBGP 20
IGP 100
IBGP 200
See: http://www.cisco.com/warp/public/105/admin_distance.pdf
2) Propagates the external routes within an as

iBGP is used to propagate routes leaned from external neighbour via eBGP to other iBGP neighbours.
IGP
1) Not affected by route flaps external to the AS.

IGP is used for the interior routes, BGP handles the external routes.
2) Propagates the internal subnets and BGP next hops.

IGP is used for the interior routes / internal subnets. BGP handles the external routes. The IGP propagates the next hops for BGP so IBGP neighbours can establish.
