Configure route targets.
vpn-target vpn-target
&<1-8> [
both
|
export-extcommunity
|
import-extcommunity
]
By default, no route targets are
configured.
4.
Set the maximum
number of active routes.
routing-table
limit
number
{
warn-threshold
|
simply-alert
}
By default, the number of active
routes ain a VPN instance is not
limited.
Setting the maximum number of
active routes for a VPN instance
can prevent the PE from learning
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.
The specified routing policy must
have been created.
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.
The specified routing policy must
have been created.
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). The
LSP tunnel takes precedence
over the CR-LSP tunnel.
The specified tunnel policy must
have been created.

policies, see "

Configuring routing on an MCE
MCE implements service isolation through route isolation. MCE routing configuration includes the
following:
•
MCE-VPN site routing configuration.
•
MCE-PE routing configuration.
On the PE, 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, configure VPN instances, and bind the VPN instances to
the interfaces connected to the VPN sites and the PE.
