Just to complement what Leigh said,
If you need your ebgp peer to see you as AS100 and you configure "router bgp
100" you don't need to use "local-AS 100"
router bgp 100
neighbor 10.10.10.2 remote-as 200
If your autonomous system were let's say AS500 (like Leigh suggested), but
you would like to fool your ebgp peer to see you as AS100 then you could use
local-AS 100
router bgp *500*
neighbor 10.10.10.2 remote-as 200
neighbor 10.10.10.2 local-AS 100
