Step Command Remarks
8. (Optional.) Configure OSPF
to redistribute the default
route.
default-route-advertise summary
cost cost
By default, OSPF does not
redistribute the default route.
This command redistributes the
default route in a Type-3 LSA. The
MCE advertises the default route to
the PE.
9. (Optional.) Configure filtering
of advertised routes.
filter-policy { acl-number |
prefix-list prefix-list-name } export
[ protocol [ process-id ] ]
By default, redistributed routes are
not filtered.
10. (Optional.) Configure the
default parameters for
redistributed routes (cost,
route number, tag, and type).
default { cost cost | tag tag | type
type } *
The default cost is 1, the default tag
is 1, and default type of
redistributed routes is Type-2.
11. Create an OSPF area and
enter OSPF area view.
area area-id
By default, no OSPF area is
created.
12. Enable OSPF on the interface
attached to the specified
network in the area.
network ip-address wildcard-mask
By default, an interface neither
belongs to any area nor runs
OSPF.
Configuring IS-IS between an MCE and a PE
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an IS-IS process
for a VPN instance and
enter IS-IS view.
isis [ process-id ] vpn-instance
vpn-instance-name
N/A
3. Configure a network
entity title.
network-entity net By default, no NET is configured.
4. Redistribute VPN routes.
import-route protocol [ process-id |
all-processes | allow-ibgp ] [ cost cost |
cost-type { external | internal } | [ level-1
| level-1-2 | level-2 ] | route-policy
route-policy-name | tag tag ] *
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.
5. (Optional.) Configure
filtering of advertised
routes.
filter-policy { acl-number | prefix-list
prefix-list-name | route-policy
route-policy-name } export [ protocol
[ process-id ] ]
By default, IS-IS does not filter
advertised routes.
6. Return to system view. quit N/A
7. Enter interface view. interface interface-type interface-number N/A
8. Enable the IS-IS process
on the interface.
isis enable [ process-id ]
By default, no IS-IS process is
enabled.
