OSPF advertise NAT pool

[Gerard Gasca]

                   Hi, maybe I'm not searching for the correct terms but I couldn't find anything on this. I have an ASA 5550 and it forms adjacency fine with 4 routers but I can't get it to advertise it's NAT pool addresses to the routers.

Say the NAT pool is 10.1.1.0/24 .  I entered the network statement for that network in the OSPF section. Am I missing something?

Thank you,

Gerry

This is not possible, unfortunately. When you enter the network command in OSPF referencing the NAT IP Pool, the OSPF conditions will not be met, mainly; having an Up/Up interface in that network.

If you really need to advertise the network via OSPF, you can create a static route and redistribute it through OSPF. I believe that is your best bet.

Thanks Kyle I'll give that a shot.

1. Add a static route to Nat Pool:
   ciscoasa(config)# route Null0 10.1.1.0 255.255.255.0 1
2. In the ospf process add active redistribution static routes
   ciscoasa(config)# router ospf 1
   ciscoasa(config-router)# redistribute static metric 1 subnets

Hello

FUI - If  10.1.1.0/24 isn’t in the route table ospf will not advertise it
