MCE. Bind GigabitEthernet 2/0/1 to VPN 1, and GigabitEthernet 2/0/2 to VPN 2. The MCE adds
a received route to the routing table of the VPN instance that is bound to the receiving VLAN
interface.
• Route exchange between MCE and PE—The MCE connects to PE 1 through Ethernet subinterfaces.
On the MCE, bind GigabitEthernet 2/0/3.1 to VPN 1, and GigabitEtherent 2/0/3.2 to VPN 2. On
PE 1, create VPN instances for VPN 1 and VPN 2. Bind GigabitEthernet 2/0/1.1 to VPN 1, and
GigabitEthernet 2/0/1.2 to VPN 2. The MCE adds a received route to the routing table of the VPN
instance that is bound to the receiving VLAN interface.
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.
