Loopbacks are advertised as "host routes", meaning they show up as /32s and not their "true" mask. To allow the route table to see the true mask you can use one of the following commands; 1. under the interface, such as interface loopback0 ip address 132.56.1.1 255.255.255.0 ip ospf network point-to-point 2. or, under the ospf process area 999 range 132.56.0.0 255.255.240.0 > b) i need to summarise these loopback address to /20 > on bbr1 This above "area 999 range" command should solve this problem also. > c) block these addresses on bbr2 from being > re-distributed into area 0 Under the ospf process, enter distribute-list 11 out access-list 11 deny 132.56.0.0 0.0.16.255 access-list 11 permit any > but at the same time allow the ospf neighbor > relationship between > bbr2 and r4 to be maintained. > > I think I can use > - route-map, filter-list and/or distribute list > > How can I resolve these issues... brief configs on > route-map etc will be > appreciated. > > Thanks in advance. > Vijay [EMAIL PROTECTED] __________________________________________________ Do You Yahoo!?
