ipv6 import-route isis level-1 into level-2
Function
The ipv6 import-route isis level-1 into level-2 command configures IPv6 route leaking from Level-1 areas to Level-2 areas.
The undo ipv6 import-route isis level-1 into level-2 command prohibits IPv6 route leaking from Level-1 areas to Level-2 areas.
By default, all Level-1 routing information, excluding information about default routes, is leaked to Level-2 areas.
Format
ipv6 import-route isis level-1 into level-2 [ filter-policy { acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name } | tag tag | direct allow-filter-policy ] *
undo ipv6 import-route isis level-1 into level-2 [ filter-policy { acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name } | tag tag | direct allow-filter-policy ] *
Parameters

Usage Guidelines
The ipv6 import-route isis level-1 into level-2 command can take effect only after IPv6 is enabled for the IS-IS process by the ipv6 enable command.
For an ACL6, when the rule command is used to configure a filtering rule, the filtering rule is effective only with the source address range that is specified by the source parameter and with the time period that is specified by the time-range parameter.
