Chenyan,

        You can use the command 'neighbor 1.2.3.4 next-hop-unchanged',
or you can modify the next-hop with a route-map:

Router BGP 1
 neighbor 1.2.3.4 route-map SET_NEXT_HOP
!
route-map SET_NEXT_HOP permit 10
 match ip address prefix-list Mr_Prefix
 set ip next-hop 5.6.7.8
route-map SET_NEXT_HOP permit 20
!
ip prefix-list Mr_Prefix permit 10.0.0.0/8

hi,guys,

Is it possible to keep the next-hop attribute of the NLRI of the
original AS when they are passing through a transit AS, and HOW?

Thanks
