Hi Csaba,

So BGP is up:

10.4.20.4/32 1:3 10.30.11.1 20/100/0/0 293 20965

I have the routes in both VRFs (CORE and VRF_CMS):

R11#show ipv4 route VRF_CMS

B 10.4.20.4/32 20/0 null@CORE:4 10.30.11.1 00:03:22

But I cannot ping 
R11#ping 10.2.20.2 vrf VRF_CMS
pinging 10.2.20.2, src="null," vrf=VRF_CMS, cnt=5, len=64, df=false, tim=1000, gap=0, ttl=255, tos=0, sgt=0, flow=0, fill=0, alrt=-1
result=0.0%, recv/sent/lost/err=0/5/5/0, took 0, min/avg/max/de

Any idea?

you dont need ipv6 at all in your core to provide ipv6 services over mpls

vpnv6 is about that for customers, labelled unicast is about to provide raw ip

moreover, if isis would capable to bring up bgp then you can even run ipv4 services without ipv4 in your core

Hi Csaba,
Yes, I   m currently taking a look to the topology that you mentioned and the BGP CTP.
However, I tried to build the simulation with VPNV4 and VPNV6 but BGP is only up for IPv4 and IPv6 if it   s directly connected.
R1#show ipv6 bgp 10 summary
neighbor                   as       ready   learn   sent   uptime
fd00:51e5::a:1:12:2   20965   false   0         0       never

fd01:30::3                20965   false   0         0       never
The first problem is that I cannot ping to fd00:51e5::a:1:12:2 from R1 and it is directly connected but OSPF shows an init state and not a full state.
R1#show ipv6 ospf 10 neighbor

Thanks Csaba! I have a simulation that is more or less working... I have the routes for R1, R3 and R4 but not for R2 I don't know why because I have the same. Anyway, it was enough for today Enjoy your weekend

well the less the more sometimes....
3 ospf processes for 1 bgp per topology seeems a bit overkill...
you need 1 ospf and 1 bgp per router and it'll be dual stack all         the way per tology
have you seeen frederic's validated design? almost the same but with rsvp-te to have
"traffic engineering" capabilities offloaded to hardware....

I remove them and I got this warning:

info cfgInit.executeSWcommands:cfgInit.java:768 line 105: "neighbor fd01:10::1 update-source loopback10" : % in other vrf

Because fd01:10::1         if the loopback of the neighbor that belongs to VRF_ATLAS.

it's just that you dont have to build parallel infrastructure with 3 parallel ospfs and bgps,

but a single core

an mp-bgp in vpnv4/vpnv6 over loopbacks

and vrfs with route-target export-imports

and kaboom, you have 3 parallel topologies and you can concentrate on pbr if mpls-vpn-extranet is not better...

I'm able to do PBR or BRIDGE-FILTER but not both at the same time even with the profile CERN_FLOW that you created the last time for us. Then, in some links we only have 1 VLAN
to use and I would like 3 VRFs (for example AMS -> CHI because they use sense-o) so my supervisor mentioned that there is one technique call QinQ to encapsulate VLANs.
