Configuring RIP between an MCE and a PE
Step
1. Enter system view.
2. Create a RIP process
for a VPN instance and
enter RIP view.
3. Enable RIP on the
interface attached to
the specified network.
4. Redistribute the VPN
routes.
5. (Optional.) Configure
the default cost for
redistributed routes.
Configuring OSPF between an MCE and a PE
Step
1. Enter system view.
2. Create an OSPF process for
a VPN instance and enter
OSPF view.
3. Disable routing loop
detection.
4. (Optional.) Configure the
OSPF domain ID.
5. (Optional.) Configure the
type codes of OSPF
extended community
attributes.
6. (Optional.) Configure the
external route tag for
imported VPN routes.
7. Redistribute the VPN routes.

Remarks

N/A
By default, RIP is disabled on
an interface.
By default, no routes are
redistributed into RIP.
The default cost is 0.

By default, routing loop detection
is enabled.
You must disable routing loop
detection for an OSPF VRF
process on the MCE. Otherwise,
the MCE does not receive OSPF
routes from the PE.
The default domain ID is 0.
The defaults are as follows:
•
0x0005 for Domain ID.
•
0x0107 for Router ID.
•
0x0306 for Route Type.
By default, no route tag is
configured.
In some networks, a VPN might
be connected to multiple MCEs.
When one MCE advertises the
routes learned from BGP to the
VPN, the other MCEs might learn
the routes, resulting in routing
loops. To avoid such routing
loops, you can configure route
tags for VPN instances on an
MCE. As a best practice,
configure the same route tag for
the same VPN on the MCEs.
By default, no routes are
redistributed into OSPF.
