BGP into IGP

Hi,

I was wondering if anyone could tell me when to use the following commands:

bgp redistribute-internal and table-map.

According to Jeff Doyle TCP/IP vol 2, table-map will preserve correct AS
path and origin info - page 256 to 259.

In the book's example the command 'bgp redistribute-internal' is not used
even though bgp is redistributed into ospf.

Can these 2 commands work together or independently of each other ?

 Will it preserve AS path and Origin info too ?

----------------------------------------------------------------------------
router ospf 300
redistribute bgp 1300

router bgp 1300
redistiriubte ospf 300 route-map get-tag

route-map get-tag permit 10
set as-path tag

-----------------------------------------------
router ospf 300
redistribute bgp 1300

router bgp 1300
table-map set-tag
redistribute ospf 300

route-map set-tag permit 10
match as-path 1
set automatic-tag

-------------------------------------------------------------------------

router ospf 300
 redistribute bgp 200
!
router bgp 200
 bgp redistribute-internal

Any help is much appreciated.

Thanks.
Paul
