Hi all, I build an OSPF config between one cisco box and a zebra openbsd.
LAN1 ---- ZEBRA == (GRE Tunnel over Internet) == CISCO ------ LAN2 Because I had some problem on the openbsd to encapsulate multicast hello packets in GRE, I used the ospf network type : non broadcast. My config is : interface Tunnel0 description Tunnel vers NICE ip address 192.168.0.2 255.255.255.252 ip mtu 1450 ip ospf network non-broadcast ip ospf cost 100 ip ospf hello-interval 10 ip ospf priority 255 tunnel source Ethernet1 tunnel destination 212.232.45.149 ! router ospf 1 router-id 192.168.2.1 log-adjacency-changes redistribute connected metric-type 1 subnets route-map CONNECTED-to-OSPF network 192.168.0.0 0.0.0.3 area 0 network 192.168.2.1 0.0.0.0 area 0 neighbor 192.168.0.1 priority 1 poll-interval 1 I don't exactely understand the behavior of the non-broadcast mode. What the purpose of the "neighbor" command ? Is it just for DR/BDR election or for neighbor discovering too ? If not, how is done the discovery (I didn't configure the neighbor command on the zebra box, and it works. moreover if I issue a non neighbor on the cisco, the command is still here) ? Are all the OSPF packets unicast ? (I take some traces, and it appears that all packets are unicast, but I want to be sure). Thanks for the help, I can't find any good documentation for NBMA ...
