OSPF configuration on Enterasys S series - default routes and passive interfaces.


I have 2 questions about OSPF configuration:

Firstly - Is there an equivalent to the Cisco command default-information originate ?
If not, how should I go about advertising a default route in a single area OSPF network.

Secondly - I see the passive-interface command, but is there an equivalent to the passive-interface default
command? I have quite a lot of routed interfaces that I want included in OSPF as passive interfaces, but I'd rather not have to go through and specify each and every one as passive. It would be much easier to set passive-interface default and then negate the command for those interfaces connected to other routers.

So you're saying that I'd use the redistribute static command to advertise the default route?

Regarding passive-int default - are you saying this command is available? I have been unable to find it either on the devices or in the CLI guides. Has it been introduced in a recent firmware?

re: redistribute static - yes. This is currently how the default route is injected into single area/area 0

passive interface default
yes, fairly new support. This has been supported since (i believe) 8.11 code release.

Hello Jon P,

regarding passive-interface default in S-series documentation:

We are correcting this in our documentation - and thank you for pointing out the oversight.

Best,

Thanks. If we're running earlier firmware which does not support the passive interface default command, is it possible to use something like
passive interface vlan.*.*
to apply the command to all interfaces?

No such command or nor similar available in older revs Jon.
