Hi Navid,

I believe that as-override command is only available in IPv4 VRF
address-family instance. Check out the link below.

ip vrf CUSTOMER_A
 rd 1:1
 route-target export 1:1
 route-target import 1:1

router bgp 1
 no synchronization
 bgp log-neighbor-changes
 neighbor 12.0.0.2 remote-as 2
 no auto-summary
 !
 address-family ipv4 vrf CUSTOMER_A
 neighbor 12.0.0.2 remote-as 2
 neighbor 12.0.0.2 activate
 neighbor 12.0.0.2 as-override
 no auto-summary
 no synchronization
 exit-address-family

Hi,

IE lab 3 SG indicates that there are 2 ways to allow a router to have a
route where its own AS was already present :

1/ on the router which receives the route, type "allowas-in"

2/ on the router which send the route, "use AS override feature" (p 236)
: what is the associated command ?

thanks,
Navid
