Using the import-route bgp4+ allow-ibgp command will redistribute both EBGP and IBGP routes. The 

redistributed IBGP routes may cause routing loops. Therefore, be cautious with this command.

acl6-number: Number of a basic or advanced ACL6 used to filter routes when they are leaking from 

Level-2 to Level-1, ranging from 2000 to 3999.  

ipv6-prefix-name: Name of an IPv6 prefix list used to filter routes when they are leaking from Level-2 to 

Level-1, a string of 1 to 19 characters.  

route-policy-name: Name of a routing policy used to filter routes when they are leaking from Level-2 to 

Level-1, a string of 1 to 19 characters.  

tag: Specifies a administrative tag number for the leaked routes, in the range of 1 to 4294967295.  

Use the ipv6 import-route isisv6 level-2 into level-1 to enable IPv6 IS-IS route leaking from Level-2 

to Level-1. 

Use the undo ipv6 import-route isisv6 level-2 into level-1 command to disable the leaking.  

The leaking is disabled by default.  

The route leaking feature enables a Level-1-2 router to advertise routes destined to the Level-2 area 

and other Level-1 areas to the Level-1 and Level-1-2 routers in the local area.
