Problem with Distance in OSPF

Hello,

 

I have some problems with changing the AD in OSPF. I am trying to change the
distance or some routes learned by a neighbor to 109. However when I see the
routing table, it seems that the AD is changed only for one network (which
is directly connected to neighnor). Please help me understand this behavior.

 

 

Rack1R5#sh run | s ospf

router ospf 1

 router-id 150.1.5.5

 log-adjacency-changes

 network 139.1.15.5 0.0.0.0 area 1

 network 139.1.25.5 0.0.0.0 area 1

 distance 109 150.1.1.1 0.0.0.0 FROM_R1 ---------------> I want to change
distance for specific networks learned from this neighbor. 150.1.1.1 is the
router id of neighbor

 

Rack1R5#sh access-lists

Standard IP access list FROM_R1

    40 permit 139.1.11.0 (3 matches)

    10 permit 139.1.2.0 (3 matches)

    50 permit 139.1.0.0 (3 matches)

    20 permit 139.1.6.0 (3 matches)

    30 permit 139.1.7.0 (3 matches)

 

Rack1R5#sh ip ospf neigh

 

Neighbor ID Pri State Dead Time Address Interface

150.1.2.2 0 FULL/ - 00:00:38 139.1.25.2
Serial0/0.52

150.1.1.1 0 FULL/ - 00:00:30 139.1.15.1
Serial0/0.51 --------------> This neighbor is connected by a point to
point frame relay sub-interface

 

 

Rack1R5#sh ip route ospf
