4. Set the maximum number of
active routes.
routing-table
limit
number
{ warn-threshold |
simply-alert
}
By default, the number of active
routes in a VPN instance is not
limited.
Setting the maximum number of
active routes for a VPN instance
can prevent the PE from storing
too many routes.
5. Apply an import routing
policy.
import route-policy
route-policy
By default, all routes matching the
import target attribute are
accepted.
Make sure the routing policy
already
exists. Otherwise, the
device does not filter received
routes.
For information about routing
policies, see Layer 3—IP Routing
Configuration Guide.
6. Apply an export routing
policy.
export route-policy
route-policy
By default, routes to be advertised
are not filtered.
Make sure the routing policy
already exists. Otherwise, the
device does not filter routes to be
advertised.
For information about routing
policies, see Layer 3—IP Routing
Configuration Guide.
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, and
CRLSP 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, do the following:
• 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, configure VPN instances, and bind the VPN instances to
the interfaces connected to the VPN sites and those connected to the PE.
