Issue
In this Lab we will configure traditional
MPLS L3 VPN , software image in use is c3725-adventerprisek9-mz.124-18 , in
addition we will configure IPv6 addressing between PEs and CEs and transport
over the IPv4 MPLS backbone , so called 6PE and 6VPE
Basic Configuration

Verification
Now
as an IPv4 MPLS L3 VPN, we already know the details needed to configure MPLS L3
VPN in addition to the below commands to ensure appropriate LDP peering on P
and PE routers
mpls
label protocol ldp
mpls
ldp router-id loopback 0 force
mpls
ip (from interface configuration mode)
The
CE-PE routing protocol is static, we defined a static route from R2 towards
R1’s loopback 0 interface and from R4 towards R4 loopback 0 interface and we redistributed
that under the address-family ipv4 vrf {Name}
Below
are some show commands to verify the connectivity between CEs and the
operational parameters involved

we can see that connectivity is achieved between CEs loopbacks
Now
let us configure IPv6 addressing on the links between CE1-PE1, CE2-PE2

respectively
CE1
ipv6

CE2
ipv6

And
from the PEs we will configure static routes back to the CEs loopback
interfaces in order to reach and redistribute into the BGP address family to
transport to the other end

PE2

the important part is how we will import these prefixes and how they will be

As
we can see from the outputs above that CE1 can reach CE2 and vice versa, the
routes on the PEs as can be noted are in the global routing table and not in a VRF,
as well we did not configure P to support IPv6 as well there are no label bindings to an IPv6 addresses in
the MPLS forwarding table of the P router, we only needed the PEs to activate
the session between their loopbacks and create the IPv6 address-family
This
is the concept of 6PE, IPv6 VPN routes are installed in the global routing table,
if we wanted to configure VRF to contain these routes, we have to configure a
new address family (address-family vpnv6) between the PEs and we have to
configure our VRF using the vrf definition {} command which supports both IPv4
and IPv6 (multiprotocol VRF) , as well we activate the type of address family
under the vrf definition {} configuration mode
Starting
from IOS 12.4(20)T (and 12.2(33)Sxx) the new command "vrf definition"
was introduced.
6VPE
Now
assuming we have changed our version to 12.4(20) and with same IPv4
configuration listed above, let us go through the configuration of 6VPE

If
we tried to configure the vrf forwarding under the interface without specifying
the address-family (either IPv4 or IPv6) under the vrf definition configuration
mode, we will be prompted for an error
PE2(config-if)#ipv6

is linked to a VRF. Enable IPv6 on that VRF first.
