NOTE
The command is run on the Level-1-2 device that is connected to an external area.
By default, routes in the Level-2 area are not leaked into Level-1 areas. After this command is
run, only routes that meet the specified conditions can be leaked into Level-1 areas.
Configure routes in Level-1 areas to leak into the Level-2 area.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
– ipv6 import-route isis level-1 into level-2 [ tag tag | filter-policy { acl6-
number | acl6-name acl6-name } ]
Routes that meet the specified conditions in Level-1 areas are leaked into the
Level-2 area based on the ACL.
Run any of the following commands as required:
– Configure a basic ACL:
a. Run:
quit
Return to the BGP view.
b. Run:
quit
Return to the system view.
c. Run
acl ipv6 { [ number ] acl6-number1 | name acl-name [ number acl-
number2 ] } [ match-order { auto | config } ]
The basic ACL view is displayed.
d. Run
rule [ rule-id ] { deny | permit } [ fragment | source { source-
ipv6-address prefix-length | source-ipv6-address/prefix-length
| any } | time-range time-name | vpn-instance vpn-instance-
name ]
A rule is configured for the basic ACL.
When the rule command is run to configure rules for a named ACL, only
the source address range specified by source and the time period specified
by time-range are valid as the rules.
When a filtering policy of a routing protocol is used to filter routes:
– If the action specified in an ACL rule is permit, a route that matches
the rule will be received or advertised by the system.
– If the action specified in an ACL rule is deny, a route that matches the
rule will not be received or advertised by the system.
– If a route has not matched any ACL rules, the route will not be received
or advertised by the system.
