Step
3. Redistribute remote site
routes advertised by the PE
into OSPF.
4. Create an OSPF area and
enter OSPF area view.
5. Enable OSPF on the
interface attached to the
specified network in the area.
Configuring IS-IS between an MCE and a VPN site
An IS-IS process belongs to the public network or a single VPN instance. If you create an IS-IS
process without binding it to a VPN instance, the process belongs to the public network.
Binding IS-IS processes to VPN instances can isolate routes of different VPNs. For more information
about IS-IS, see Layer 3—IP Routing Configuration Guide.
To configure IS-IS between an MCE and a VPN site:
Step
1. Enter system view.
2. Create an IS-IS process for a
VPN instance and enter
IS-IS view.
3. Configure a network entity
title.
4. Create the IS-IS IPv4 unicast
address family and enter its
view.
5. Redistribute remote site
routes advertised by the PE
into IS-IS.
6. Return to system view.
7. Enter interface view.
8. Enable the IS-IS process on
the interface.

Remarks
a router ID for the OSPF process.
An OSPF process can belong to
only one VPN instance, but one
VPN instance can use multiple
OSPF processes to advertise
VPN routes.
By default, no routes are
redistributed into OSPF.
By default, no OSPF areas exist.
By default, an interface neither
belongs to any area nor runs
OSPF.
Remarks
N/A
Perform this configuration on the
MCE. On a VPN site, configure a
common IS-IS process.
By default, no NET is configured.
By default, the IS-IS IPv4 unicast
address family is not created.
By default, IS-IS does not
redistribute routes from any other
routing protocol.
If you do not specify the route
level in the command, the
command redistributes routes to
the level-2 routing table by
default.
N/A
N/A
By default, no IS-IS process is
enabled on the interface.
