Static ARP entry and OSPF routing

Asked by fr0x in OpenBSD, Unix Networking

Tags: , ,

Hello, Experts!

I am running small OSPF network on my OpenBSD routers for client traffic management with trivial "security" policy - static arp entries for single computer which is connected to router. The problem is redistribution of those static arp entries over OSPF network like /32 route.

For example, if I add static arp entry on BOX A like the following:
box a# arp -s 195.195.195.1 00:00:00:00:00:FF

.. and thanks to OSPF, automatically I get route on BOX B like the following:
box b# netstat -rn
195.195.195.1/32  195.195.1.1     UG2         0        0      -   fxp0

How to avoid this? Would love to get rid of those "P2P routes".

=====

Platform OpenBSD 4.2 with ospfd (base).

# cat /etc/ospfd.conf

router-id 195.13.171.241

redistribute connected set { metric 1 type 1 }
redistribute static set { metric 2 type 1 }

area 0.0.0.0 {
        interface fxp0
