Configuring Routing On An Mce; Configuring Routing Between An Mce And A Vpn Site - HP 6127xlg Configuration Manual

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.

Configuring routing between an MCE and a VPN site

You can configure static routing, RIPng, OSPFv3, IPv6 IS-IS, or EBGP 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 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
1. Enter system view.
2. Configure an IPv6 static
route for an IPv6 VPN
instance.
3. (Optional.) Configure
the default preference
for IPv6 static routes.
Configuring RIPng between an MCE and a VPN site
A RIPng process belongs to the public network or a single IPv6 VPN instance. If you create a RIPng
process without binding it to an IPv6 VPN instance, the process belongs to the public network. By
configuring RIPng process-to-IPv6 VPN instance bindings on a MCE, you allow routes of different VPNs
to be exchanged between the MCE and the sites through different RIPng processes, ensuring the
separation and security of IPv6 VPN routes.
For more information about RIPng, see Layer 3—IP Routing Configuration Guide.
To configure RIPng between an MCE and a VPN site:
Command
system-view
ipv6 route-static vpn-instance
s-vpn-instance-name ipv6-address prefix-length
{ interface-type interface-number
[ next-hop-address ] | nexthop-address [ public ] |
vpn-instance d-vpn-instance-name
nexthop-address } [ permanent ] [ preference
preference-value ] [ tag tag-value ] [ description
description-text ]
ipv6 route-static default-preference
default-preference-value
461
Remarks
N/A
By default, no IPv6 static
route is configured.
Perform this configuration
on the MCE. On a VPN
site, configure normal
IPv6 static routes.
The default preference for
IPv6 static routes is 60.
