Configuration Roadmap
The configuration roadmap is as follows:
1.
Configure IGP on the backbone network so that PEs can learn the loopback address of each
other. Create MPLS LSPs between the PEs.
2.
Create a VPN instance on UPE and set up an EBGP adjacency between UPE and CE1.
Create a VPN instance on PE and set up an EBGP adjacency between PE and CE2.
3.
Set up an MP-IBGP adjacency between UPE and SPE, and between PE and SPE.
4.
Create a VPN instance on the SPE and set the UPE as its under layer PE. Configure the
UPE to advertise the default route of the VPN instance.
