[c-nsp] Limiting networks announced on special link of OSPF

[Joe Shen]

Hi,

Can I restricting networks advertised on one link in
OSPF?


My situation:


   Cat6509-a ------------------  Cat6509-b
               (Vlan3, 8 on trunk)


both Cat6509 run OSPF. Vlan 3 is a vlan planned for
server installation, while Vlan 8 is interconnection.
Subnet of Vlan 3 is planned as a NSSA area which
connects to area 0, while both catalyst6509 belong to
area 0. There is only one ospf process configed on
each catalyst6509, and there is logical interface
Vlan3 on both catalyst6509.


After setting up vlan3 interface on L3 module, I
noticed catalyst6509-a and catalyst6509-b establish
ospf neighbor relationship. And, route from 6509-b to
some subnet on 6509-a point to vlan 3 and vlan8. but,
i just don't want vlan3 on trunk link to carry any
traffic beside those inside vlan3. 

How can I do it? 

thanks

Joe
