Manipulating the installation of E2 routes

Hi,

I have three router R1,R2 and R3.They are configured with ospf
point-to-multipoint network type.

I get one E2 on R1 from both the R2 and R3 with same metrics.

R1 installs both the routes in the routing table.

My requirement was to have only the route from R2 installed in the routing
table.

I used to following command under the routing process to achieve it:

distance 109 <router-id of r2> <wild-card mask> <acl matching the network>

This command was not taking effect and both the routes were still installed
in the R1s table.

But as soon as R3 stopped advertising the route,R1 installed the route from
R2 with a distance of 109.

Is this an expected behavior?Am I missing anything here?

Thanks
With regards
Suryakant
