a. Assume VPN_A and VPN_B use the same IP block/address space. How is this achieved?
RD- Route distinguisher allows different VPNs to use the same address space. RD is a 64 bit
prefix which is added in front of the IPv4 address to make potentially same IPv4 addresses
globally unique. Rd is used to identify VPN as each VPN is assigned a unique RD.
b. What is the purpose of using BGP?
When 64 bits of RD prefix is added to 32 bits of IPv4 address than it results into 96 bits of
VPNv4 addresses. VPNv4 addresses are exchanged between PE routers via BGP. To support
address families other than IPv4, another form of BGP is used known as MP-BGP.
c. For implementing the above VPNs what is the contribution of MPLS other than traffic
engineering?
Label stacking mechanism was introduced in MPLS VPN. PE ingress router attached two labels
to an unlabelled IP packet it receives. One of this is for LSP and other one for VPN. First label is
used to transfer the packet to egress router through label swapping in the MPLS network. Core
routers only perform label lookup. Second label is used by the egress router to match the VPN
route to CE. To learn BGP updates in the MPLS VPN network loopback interface on each router
is used.
d. Ping the loopback address of the peer router including the loopback addresses of VPNs
and capture the output?
ICMP echo request from 10R2 to 9R2
ICMP echo reply from 9R2 to 10R2 in response to ICMP echo request
Outputs for the following commands:

Show mpls interfaces: Shows mpls enabled interfaces as we can see in the outputs below for
routers 9R4 and 9R1
Show mpls ldp neighbor: shows the active mpls neighbors as we can see in the output below
for router 9 R4, it has 2 mpls neighbors 9R1 and 10R4.
Show mpls ldp bindings: shows the mpls label bindings i.e local label bounded and remote
label bounded.
Show mpls forwarding table: shows the local and outgoing labels along with the outgoing
interface and next hop.
