Figure 3 Network diagram for the MCE feature
You can configure static routes, RIP, OSPF, IS-IS, EBGP, or IBGP between an MCE and a VPN site
and between an MCE and a PE.
NOTE:
To implement dynamic IP assignment for DHCP clients in private networks, you can configure
DHCP server or DHCP relay agent on the MCE. When the MCE functions as the DHCP server, the
IP addresses assigned to different private networks cannot overlap.

Configuring VPN instances
VPN instances isolate VPN routes from public network routes and routes among VPNs. This feature
allows VPN instances to be used in network scenarios in addition to MPLS L3VPNs.
All VPN instance configurations are performed on PEs or MCEs.
