Configuring Routing On An Mce - H3C S6800 Series Configuration Manual

Step
2. Enter VPN instance view or
IPv6 VPN view.
3. Configure route targets.
4. Set the maximum number of
active routes supported.
5. Apply an import routing
policy.
6. Apply an export routing
policy.

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, disable routing loop detection to avoid route loss during route
calculation, and disable route redistribution between routing protocols to save system resources.
Before you configure routing on an MCE, complete the following tasks:
Command
•
Enter VPN instance view:
ip vpn-instance
vpn-instance-name
•
Enter IPv6 VPN view:
address-family ipv6
vpn-target vpn-target&<1-8>
[ both | export-extcommunity |
import-extcommunity ]
routing-table limit number
{ warn-threshold | simply-alert }
import route-policy route-policy
export route-policy route-policy

Remarks
Configurations made in VPN
instance view apply to both IPv4
VPN and IPv6 VPN.
IPv6 VPN prefers the
configurations in IPv6 VPN view
over the configurations in VPN
instance view.
By default, no route targets are
configured.
By default, the maximum number of
active routes for the 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.
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.
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.

policies, see Layer 3—IP Routing
