Configuring Routing On An Mce; Route Exchange Between An Mce And A Vpn Site - HP 3600 v2 series Configuration Manual

By establishing multiple tunnels between two MCE devices and binding the tunnel interfaces with VPN
instances, you can make the routing information and data of the VPN instances delivered to the peer
devices through the bound tunnel interfaces. According to the tunnel interfaces receiving the routes, an
MCE device determines the VPN instances that the routes belong to and advertises the routes to the
corresponding sites. As shown in
devices deliver the routing information and data of VPN 1 through the tunnel.
An MCE can also be used in a tunneling application as shown in
remote CEs through tunnels. In this scenario, the CE devices only need to receive and advertise routes as
usual, while the MCE advertises and receives VPN routing information based on the bindings between
tunnel interfaces and VPNs.

NOTE:
MCE devices in a tunneling application can exchange VPN routing information with their peer MCE
devices or CE devices directly, just as MCE devices in an MPLS L3VPN application do with the
corresponding PEs. For more information, see
GRE tunnel, IPv4 over IPv4 tunnel, and IPv4 over IPv6 tunnel support MCE.
For introduction and configuration of tunnel types, see

Configuring routing on an MCE

Interface-to-VPN-instance binding enables MCEs and PEs to determine the sources of received packets
and then forward the packets according to the routing information concerning the corresponding VPNs.
MCE routing configuration includes:
• MCE-VPN site routing configuration
MCE-PE routing configuration
•

Route exchange between an MCE and a VPN site

An MCE can adopt the following routing protocols to exchange VPN routes with a site:
Static route
•
• RIP
OSPF
•
IS-IS
•
