[c-nsp] ospf distance

[Manu Chao]

I want to change OSPF administrative distance for ospf-external-type-2-only
routes from a specific OSPF neighbor only.

option 1: changing distance using distance command
I know it is possible to change OSPF distance using "distance command" for a
neighbor globally or using standard ACL BUT it is not possible to
restrict-to-ospf-external only ;(

option 2:changing distance using distribute-list command
I try to use distribute-list in with a route-map BUT it is not possible to
set distance inside a route-map :(

I need help. Is it possible? Is there any hint?

Thanks for your help.

My config look like as follow:

option 1:
router ospf 1
router-id 1.1.1.1
distance 19 2.2.2.2 0.0.0.0 ospf-e2-only
!
ip access-list standard ospf-e2-only
permit ?

Router(config-std-nacl)#permit ?
  Hostname or A.B.C.D  Address to match
  any                  Any source host
  host                 A single host address

--> NOT POSSIBLE TO SPECIFY OSPF EXTERNAL E2 ROUTES :(

option 2:
router ospf 1
router-id 1.1.1.1
distribute-list set-distance-to-ospf-external-2-only in

route-map set-distance-to-ospf-external-2-only
match route-type match route-type external type-2
set ?

Router(config-route-map)#set ?
