Figure 7 on page 88 shows a standard MPLS VPN network. Routers CE1 and CE2 are
customer edge routers, PE1 and PE2 are provider edge routers, and P0 is a provider core
router. Several Layer 3 VPNs are configured across this network, as well as one Layer 2
VPN. Interfaces are shown in the diagram and are not included in the configuration
example that follows.

On Router CE1, configure the following protocols on the logical interfaces of
OSPF on unit 101, RIP on unit 102, BGP on unit 103, and IS-IS on unit 512. Also configure
graceful restart, BGP, IS-IS, OSPF, and RIP on the main instance to be able to connect
to the routing instances on Router PE1.
