EXOS: OSPF "passive-interface default" needed

[M_Nees]

Currently i configure OSPF on X870 Switches (recent EXOS 22.2.x).

I am looking for a command for setting all vlan to "passive default" like i do it on EOS or Cisco.

Currently i do manually vlan for vlan only.

configure ospf add vlan VLAN-0111 area 172.16.1.0 passive
configure ospf add vlan VLAN-0113 area 172.16.1.0 passive
configure ospf add vlan VLAN-4001 area 172.16.1.0
Is there no default passive statement ?

Instead of adding every vlan as passive you could just enable ospf on one vlan and then do export direct to export all direct connected vlans into ospf.

Oscar suggests using redistribution of connected interfaces instead of adding the interface as passive to OSPF. This adds one type 5 LSA for every connected interface to the LSDB of every normal area.

OK, thanks that explain it ...
Nice mechanism to achieve the goal.

A big disadvantage for me is that in routing table all directed routes a marked as external. That makes routing table unclear / confusing. Normally i do not want this.
So i my projects i avoid this (if i can) ...

So having "passive-interface default" is a needed / missed Feature in current EXOS.

Hello Matthias,

it is very simple, add the vlan where you have ospf neighbors as normal to ospf.
To advertise all your IP vlans into ospf:

enable ospf export direct cost 10 type ase-type-1 (or type 2).

This will advertise all your direct connected subnets (all your routed vlans) to be advertised by OSPF as external ase-type-1 or 2 routes.

sounds interessting - but some explanation or example needed ...
