Step Command

7.
Apply a tunnel policy to the
VPN instance.
tnl-policy
tunnel-policy-name
By default, only one tunnel is
selected (no load balancing) in
this order: LSP tunnel, GRE
tunnel, and CR-LSP tunnel.
The specified tunnel policy must
have been created.
For information about tunnel
policies, see "Configuring tunnel
policies."
Configuring routing on an MCE
An MCE implements service isolation through route isolation. MCE routing configuration includes the
following:
•
MCE-VPN site routing configuration.
•
MCE-PE routing configuration.
On a PE in an MCE network environment, perform the following tasks:
•
Disable routing loop detection to avoid route loss during route calculation.
•
Disable route redistribution between routing protocols to save system resources.
Before you configure routing on an MCE, perform the following tasks:
•
On the MCE, configure VPN instances, and bind the VPN instances to the interfaces connected
to the VPN sites and those connected to the PE.
•
Configure the link layer and network layer protocols on related interfaces to ensure IP
connectivity.
Configuring routing between an MCE and a VPN site
You can configure IPv6 static routing, RIPng, OSPFv3, IPv6 IS-IS, or EBGP between an MCE and a
VPN site.
Configuring IPv6 static routing between an MCE and a VPN site
An MCE can reach a VPN site through an IPv6 static route. IPv6 static routing on a traditional CE is
globally effective and does not support address overlapping among VPNs. An MCE supports binding
an IPv6 static route with an IPv6 VPN instance, so that the IPv6 static routes of different IPv6 VPN
instances can be isolated from each other.
To configure IPv6 static routing between an MCE and a VPN site:
Step Command

By default, no IPv6
static routes are
configured.
Perform this
configuration on the
MCE. On a VPN site,
configure normal IPv6
static routes.
