Redistributing IPSEC sessions on the Pix

Hi,

How does one make the PIX redistribute via RIP its VPN connections?

The routes should be established dynamically as the IPSEC tunnels get built up and torn down.

Thanks in advance for any insight.

Regards

Mathew

We have a similar question.

In one office we use a 2651 with a AIM-VPN module to terminate the VPN clients, the route for the client is then entered into the local routing table using ‘reverse-route’ on the crypto map. Distribution is then by EIGRP or OSPF (or RIP if you really want) as per a static route.

crypto dynamic-map mapname 10

set transform-set myset

reverse-route

!

router ospf 100

log-adjacency-changes

redistribute static metric 200 subnets route-map ospf_add

network 192.168.1.0 0.0.0.255 area 0.0.0.0

!

ip local pool vpnippool 192.168.2.1 192.168.2.254

!

access-list 50 permit 192.168.2.0 0.0.0.255

route-map ospf_add permit 20

match ip address 50

This works perfectly. In another office we have a PIX515E-DMZ to terminate the VPN clients.

ip local pool vpnpool1 192.168.4.1-192.168.4.254

What we want to be able to do is also redistribute the VPN routes via OSPF on the PIX. I read something about RRI being included in version 7 but there are still a couple of bugs that need to be sorted out.
