Question

SIMULATION 2 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. Topology PE1 CE1 CE2 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.

Options

  • AA 6to4 tunnel is needed to transmit IPv6 traffic between customer sites over an MPLS SP core.
