Guidelines
This is a lab item in which tasks will be performed on virtual devices.
Refer to the Tasks tab to view the tasks for this lab item
Refer to the Topology tab to access the device console(s) and perform the tasks.
Console access is available for all required devices by clicking the device icon or using the
tab(s) above the console window.
All necessary pre-configurations have been applied.
Do not remove any existing configurations from the devices, only those necessary to make the
appropriate changes required to fulfill the listed tasks.
Do not change the enable password or hostname for any device.
Save your configurations to NVRAM before moving to the next item.
Click Next at the bottom of the screen to submit this lab and move to the next question.
When Next is clicked, the lab closes and cannot be reopened.
Tasks
CE1 and CE2 are IPv6 Customer Premise Equipment of two customers that communicate with each other through the MPLS L3VPN core comprising Provide Edge PE1, PE2, and route- reflector RR.
Perform the below configuration and verification tasks as noted.
1. Modify the PEs to allow the CEs to communicate with each other over their Loopback 0 addresses.
2. Modify PE1 to receive CE2's loopback1 address and advertise to CE1.
Initial configuration with IPv6 addressing has been completed. Do not change the configurations except to fulfill the abovementioned tasks. Apply the solution with the minimum configuration.

Correct Answer:
On PE1 and PE2:
1. Under address-family vpnv6
neighbor 10.3.3.3 activate
Brings up the MP-BGP session to RR for IPv6 routes.
neighbor 10.3.3.3 send-community extended
Ensures the Route Distinguisher/RT are carried so remote PEs know which VRF to install these routes into.
2. Under address-family ipv6 vrf ABC
neighbor <CE-link-IPv6> activate
(If not already present) activates the PE-CE IPv6 BGP neighbor so the PE will receive the CE's Loopback-0/32.
redistribute connected
Picks up the CE's directly-connected loopback subnet on the PE and advertises it into the MP- BGP IPv6-VPN (vpnv6) table.
