Configuring routing on an MCE
MCE implements service isolation through route isolation. MCE routing configuration includes:
• MCE-VPN site routing configuration
• MCE-PE routing configuration
On the 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:
• Configure VPN instances, and bind the VPN instances with the interfaces connected to the VPN
sites and the PE.
• Configure the link layer and network layer protocols on related interfaces to ensure IP connectivity.
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 thus does not support address overlapping among VPNs. An MCE supports binding a static
route with 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:
Ste

Command
Remarks
1. Enter system view.
system-view N/A
2. Configure a static route
for a VPN instance.
• ip route-static dest-address { mask | mask-length }
{ gateway-address | interface-type
interface-number [ gateway-address ] |
vpn-instance d-vpn-instance-name
gateway-address } [ preference preference-value ]
[ tag tag-value ] [ description description-text ]
• ip route-static vpn-instance
s-vpn-instance-name&<1-6> dest-address { mask |
mask-length } { gateway-address [ public ] |
interface-type interface-number
[ gateway-address ] | vpn-instance
d-vpn-instance-name gateway-address }
[ preference preference-value ] [ tag tag-value ]
[ description description-text ]
Use either command
as needed.
Perform this
configuration on the
MCE. On a VPN site,
configure a normal
static route.
3. Configure the default
precedence for static
routes.
ip route-static default-preference
default-preference-value
Optional.
60 by default.
Configuring RIP between an MCE and a VPN site
A RIP process belongs to the public network or a single VPN instance. If you create a RIP process without
binding it to a VPN instance, the process belongs to the public network. Binding RIP processes to VPN
instances can isolate routes of different VPNs.
