You can not establish neighbors over secondary addresses.
http://www.cisco.com/warp/public/104/2.html As a workaround try configuring a tunnel for each secondary ip subnet and configure ospf on the tunnel interfaces. --- On Wed, 11/6/08, Masood Ahmad Shah <[EMAIL PROTECTED]> wrote: From: Masood Ahmad Shah <[EMAIL PROTECTED]> Subject: [c-nsp] OSPF on Secondary IP addresses. To: [email protected] Date: Wednesday, 11 June, 2008, 2:24 PM Can OSPF establish as neighbors on secondary addresses? Do not have any luck unless the OSPF network interface is primary. Any ideas why and how do we go around this? What if a ROUTERA is connected to a wireless bridge which is serving multiple sites . Or there can be many other situation when you need to build adjacency on secondary IP address instead of primary IP. Oops I can't find any parameter (when I configure secondary address on Cisco Router) like preferred/primary . thanks to juniper guys for providing it ;) J Thanks in advance.
