the LOCAL-AS is used to present to your neighbor a different AS then your
own and the no-prepand will remove completely your own BGP AS.
so if you have
R1
router bgp 100
nei 2.2.2.2 remot 200
R2
router bgp 200
nei 1.1.1.1 remot 600 <-- here you see that R2 is trying to peer with you on
AS 600 although R1 is in AS100
So you can
R1
router bgp 100
nei 2.2.2.2 remot 200
nei 2.2.2.2 local-as 600
if you inject a network R2 will see the route as if it came from:
*>1.1.10.10 100 600
but if you add the
nei 2.2.2.2 local-as 600 no-prepand then you will see:
*>1.1.10.10 600
I hope it was clear enough
