private routes to the routing tables of corresponding VPN instances.
•
Route exchange between MCE and VPN site—Create VPN instances VPN 1 and VPN 2 on
the 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
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 GigabitEthernet 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 and PE add a received route to the
routing table of the VPN instance that is bound to the receiving 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.
