R6 is advertising 2001:6:0:6::/64 and 2001:6:0:60::/58.
But those prefixes are suppressed when aggregate with 2001:6:0:60::/57 since those are fall with the aggregate prefix.

IPv6 Routing with OSPFv3(Summarization and virtual-link)

In this lab, R4 will announce 2001:4::4/128 prefix into area 24.
When the advertisment reach ABR(R2) of area 24, R2 will summarize it into /64.
Likewise, R1 is also redistributing 2001:1::1/128 route into OSPF domain, since R1 is the ASBR itself, we can summarize it on R1. In this case, we will summarize it into /64.
R3 is not connecting to backbone area, R3 is announcing 2001::3/128 into area 3. The advertisement cannot reach to the rest of the OSPF domain.
In order to reach every other routers, R3 needs to be connected to backbone area which is area 0, so we will build virtual link between R1 and R3 to extend the backbone area to R3.

Carrier-Supporting-Carrier Section

 

In this lab, AS1 is the carrier AS.
Fe2/0 of R1 and R3 is configured under vrf one and connected to R4 and R6 respectively.
Between R1 and R4, ldp is used for label binding, between R3 and R6, bgp is used for label binding with the command "neighbor x.x.x.x send-label"
In AS2, R5 and R7 are vpnv4 peers and provide l3vpn service to R15 and R16.

Inter-AS MPLS VPN Option 2C Section(Through AToM AS2 Link)

By this time, R9 and R11 have a direct layer 2 connection through AS2.
AS3 of R8 and AS4 of R10 will peer bgp vpnv4 session.
In order to do so, we need TCP connection and label switch path(R8>R9>R11>R10) between the loopback networks of R8 and R10.
Between R9 and R11, bgp will be used to map the labels.

InterAS MPLS VPN Section(back-up link through NNI)

In this section, there will be another bgp vpnv4 session between R8 and R10 over NNI AS.
First of all, create another loopback interface on R8 and R10 each and advertise those networks under bgp ipv4 unicast to NNI AS.
Then create a tunnel connecting R8 and R10 over which we will configure bgp vpnv4 session.
Since the link through NNI is considered back-up, so we will configure a route-map with local-preference 200 that will make the path through AS 2 as the primary when applied.

L3VPN QOS PIPE MODE

In this lab, I don't apply proper QOS on CE routers except marking IPP bit.
We will consider only traffic flow direction from R5 towards R6.
We assume there is no congestion in the core, and there is no QOS configuration for the core network.
We will focus only on PE routers for this topic.

Verification

-When packets are transmitted from  R5 towards R6, packets will be marked IPP bit accordingly as policy defined on R5. Once those packets enter MPLS network, ingress PE (R1) will mapped IPP to MPLS EXP bit and apply proper treatment as per SLA. In this configuration mode, egress PE(R4) will not modifed original IPP bit when it forwarding out to CE(R6), say, if R5 sends packets with IPP bit 3, R6 will receive packets with the same IPP bit. In order to test this, I created ACL and apply on R6 interface connecting to R4.

-Now let's check MPLS packets are marked and switched correctly in core network.
In order to test this, I captured the packets on the link between R1 and R2.

 R5#ping 192.168.46.6 source loopback 1 repeat 2
!!

-On ingress PE(R1), I limit incoming traffic from CE router at 8M. Anything above 8M will be dropped. Within that 8M limit, I even control the IPP5 traffic not to go above 2M.
-On egress PE(R4), I shape the traffic up to 8M. Within that 8M queue, I give priority(latency guarantee) to IPP5 traffic and police at 2M. And also guarantee 2M and 3M to IPP3 and IPP1 streams accordingly.
Since this is gns3 lab, I can't test it to prove my config works as it is intended.

JUNOS config is not the actual one involved in this lab.
It is the similar configuration providing MPLS QOS treatment in the core.
