Configuring Routing On An Mce; Configuring Routing Between An Mce And A Vpn Site - HP FlexFabric 5940 Configuration Manual

Step
3. Configure route targets.
4. Set the maximum
number of active routes.
5. Apply an import routing
policy.
6. Apply an export routing
policy.

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.

Configuring routing between an MCE and a VPN site

You can configure static routing, RIP, OSPF, IS-IS, EBGP or IBGP between an MCE and a VPN site.
Configuring static routing between an MCE and a VPN site
An MCE can reach a VPN site through a static route. Static routing on a traditional CE is globally
effective and does not support address overlapping among VPNs. An MCE supports binding a static
route to a VPN instance, so that the static routes of different VPN instances can be isolated from
each other.
To configure a static route to a VPN site:
Command
b. address-family ipv4
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
view.
By default, no route targets are
configured.
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.
By default, all routes matching the
import target attribute are
accepted.
The specified routing policy must
have been created.

policies, see Layer 3—IP Routing
Configuration Guide.
By default, routes to be advertised
are not filtered.
The specified routing policy must
have been created.

policies, see Layer 3—IP Routing
Configuration Guide.
