hello, group,
Trying to get rid of /32 routes in OSPF, but failed.
Here is the simple scenario
R1 (10.1.123.1/24) -------FR Cloud-------- (10.1.123.3/24) R3
Both are in area 0 and using point-to-multipoint, so /32 routes show up on
both R1 and R3, which means R1 has a 10.1.123.3/32 route in addition to
10.1.123.0/24 (connected) route. Of course, you may suggest we use
broadcast, and the route will go away. But is there anyway to get rid of /32
routes and use p-2-m network type?
The way I use distribute-list is as follows, but it didn't filter out /32
routes
r1
==============================================================
router ospf 1
log-adjacency-changes
network 0.0.0.0 255.255.255.255 area 0
distribute-list 101 in Serial0
access-list 101 deny ip host 10.1.123.3 host 255.255.255.255
access-list 101 permit ip any any
==============================================================
Shall we use prefix-list? and how?
thanks.
Sean Wu
