Issue 01 (2011-07-15)
Set up MP-IBGP connections between the PEs and RR so that the PEs do not need to set
up an MP-IBGP connection.
Set up EBGP connections between the PEs and CEs.
Set up an MPLS LSP on the public network and enable MPLS LDP on the devices and
interfaces along the LSP.
Configure RR to accept all the VPNv6 routing information without filtering the routing
information based on VPN targets. Then the RR can save all the VPN-IPv6 routes sent
from PE1 and PE2 and advertises the VPN-IPv6 routes to the PEs.
MPLS LSR-IDs of PEs and RR
Names, RDs, and VPN targets of the VPN instances created on PE1 and PE2
Routing protocol used to exchange routing information between the PEs and CEs (EBGP
in this example)
Convergence priorities of the routes in the VPN instances
Name of the RD filter and name of the routing policy
Configure an IGP protocol on the MPLS backbone network to implement interworking of
devices along the LSP.
OSPF is used as the IGP protocol in this example. The configuration procedure is not
mentioned here.
NOTE
The address of the loopback interface, which functions as the LSR ID, must be advertised.
After the configuration, devices along the LSP can learn the address of the loopback
interface of each other.
Take the display on PE1 as an example.
