R2511-HP MSR Router Series MPLS Configuration Guide(V5)

149
Before you configure routing on an MCE, complete the following tasks:
• Configure VPN instances, and bind the VPN instances to 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
p
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 the 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.
To configure RIP between an MCE and a VPN site:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Create a RIP process for a
VPN instance and enter RIP
view.
rip [ process-id ] vpn-instance
vpn-instance-name
Perform this configuration on the
MCE. On the VPN site, create a
normal RIP process.
