VPN 3030 and OSPF configuration

Current Configuration:

-----------------------

VPN_Concentrator_3030_Public_Interface -----> 6509 (vlan int 999) VPN_Concentrator_3030_Private_Interface ------> 6509 (vlan int 888)

We are not following Cisco's symantic of public, private and external interfaces suggested in documentation.

Private interface is only used for Managemnt.

5 groups are configured on Concentrator. Aggregate block is 172.31.0.0/24

Static route is installed on 6509. # ip route 172.31.0.0 255.255.255.0 PUBLIC_INTERFACE_OF_CONCENTRATOR

Everything works.

Desired Configuration:

----------------------- We would like to have OSPF between 6509 and Concentrator, instead of using static routes. Enabled OSPF on PUBLIC_INTERFACE_OF_CONCENTRATOR. Reverse Route Ijection: is setup properly and have

172.31.0.0/255.255.255.0 in hold down routes.

Problem:

-------- OSPF is up between 6509 and PUBLIC_INTERFACE_OF_CONCENTRATOR. Concentrator gets all the Routes from 6509. But, Concentrator is NOT feeding 172.31.0.0/24 routes in OSPF. Thus

6509 is NOT seeing 172.31.0.0/24 routes from Concentrator.

Any pointers would be appreciated.

Thanks.
