VPWS-EVPN eBGP?

Hey folks,

I have setup a VPWS-EVPN between two iBGP speakers within AS100:

asr9k-3

router bgp 100
!
address-family l2vpn evpn
!
neighbor 102.102.102.102
remote-as 100
update-source Loopback0
address-family l2vpn evpn
!
l2vpn
xconnect group vpws
p2p vpws-xc
interface GigabitEthernet0/0/0/1
neighbor evpn evi 101 target 101 source 102

 

asr9k-2

router bgp 100
!
address-family l2vpn evpn
!
neighbor 103.103.103.103
remote-as 100
update-source Loopback0
address-family l2vpn evpn
!
l2vpn
xconnect group vpws
p2p vpws-xc
interface GigabitEthernet0/0/0/1
neighbor evpn evi 101 target 102 source 101
!

everything works, at least in theory given that ASRv9000 does not support forwarding plane traffic for l2vpn services (right?). I haven't attached anything to those G0/0/0/1 interfaces (yet) but the xconnect is up

I know this might sound a weird question, however, is there any way such a VPWS-EVP could be setup between different ASes? That is; would I be able to run a eBGP VPWS-EVP?

 

I have tried between AS100 AS300, and given the RT seems to be computed using the local AS, that is DENIED due to RT missed match, here's the output on the PE in AS100:

Thanks all in advance,

 

Cheers, L.
