Hi,
I am having some trouble getting ospfd working as I would like it.
1) I have a VLAN trunk on box 2 (rl2 interface), where the physical interface
has no IP address. It has 12 vlandevs which are each gateways to various
networks. I would like each of these vlandevs to show up as the next hop when
viewing rib from another connected router.
2) I entered interface vlan2 in ospf area 0.0.0.1, which is exchanging all 12
vlan routes with box3.
3) If I enter other vlan interfaces into area 0.0.0.1 on box2 (vlan3 { passive
} ), I suffer some ospf problems in area 0.0.0.0 on my gw (box1). Basically,
what happens is that I can reach the gw from box2 and box3 but not from
machines connected to vlan3 on box2...
4) On box3, all routes show up with next-hop of 10.1.0.1 (vlan2 on box2),
instead of the IP addresses of the respective vlan interfaces. I want the real
gateways to show up as next-hops.
