In ASR1000, importing path from global to VRF will import all available path into VRF itself depend on route-map too. For example if you have 3 paths for one prefix, no matter the as-path it will import all 3 paths. But in ASR9K XR OS seems very different, it import only one and if you set maximum-path that will import the number you set. And by default it will import only it is has same local-pref and same as-path length. I tried all 'bgp bestpath' options available and unable to get same result AS1000 gave which allow me to get the prefix path in the VRF whatever the local-pref and as-path length is.
These are my configuration
vrf Test
rd 65432:4
address-family ipv4 unicast
import from default-vrf route-policy TestImport
import route-target
65432:4
!
export route-target
65432:4
!
maximum prefix 5000000 80
!
!
route-policy TestImport
done
end-policy

router bgp 911
vrf Test
rd 65432:4
bgp redistribute-internal
address-family ipv4 unicast
distance bgp 200 200 200
maximum-paths ebgp 3 order igp-metric
redistribute connected

Any clue which option should I add to ignore as-path length and local-pref(set for default-vrf) ?
