On the srx is the interface vlan.3 assigned to a security zone where ospf is enabled as a permitted protocol?
Check the settings under host-inbound-traffic
And confirm the interface is assigned to a configured zone under interfaces
If both of these are good, have a look for logs in the trace options files for this interface
show log debug-ospf

Subject: OSPF3 - 1 of 2 neighbor can't be seen from one side
Hi team,
I would like to resolve the issue OSPF3 stack in init state.
Here is the topology graph.
SRX240 - gateway / 12.1X46-D65.4
*OSPF3 area 0.0.0.0 with vlan.2
*OSPF3 area 0.0.0.1 with vlan.3
|
| trunk vlan 2 and 3
|
EX3200 - sw01 / 14.1X53-D49.1
*VR1 - vlan.2
*OSPF3 area 0.0.0.0 with vlan.2
*VR1 - vlan.3
*OSPF3 area 0.0.0.1 with vlan.3
On vlan.2, they completed neighbor negotiation, and we can see the state is "Full".
root@gateway> show ospf3 neighbor
ID Interface State Pri Dead
10.0.2.2 vlan.2 Full 128 39
Neighbor-address fe80::3e94:d5ff:xxxx:xxxx
root@SW01> show ospf3 neighbor instance VR1
ID Interface State Pri Dead
10.0.0.1 vlan.2 Full 128 36
Neighbor-address fe80::52c5:8dff:yyyy:yyyy
However, on vlan.3, we can't see any neighbor on SRX240 regarding vlan.3, and EX3200 is stacking in init state.
root@gateway> show ospf3 neighbor
ID Interface State Pri Dead
10.0.2.2 vlan.2 Full 128 39
Neighbor-address fe80::3e94:d5ff:xxxx:xxxx
root@SW01> show ospf3 neighbor instance VR2
ID Interface State Pri Dead
10.0.0.1 vlan.3 Init 128 32
Neighbor-address fe80::52c5:8dff:yyyy:yyyy
In my thought, SRX240 should detect neighbor both on vlan.2 and vlan.3 but it doesn't.
Do you have any idea to resolve?
Here is the configuration around ospf3.
SRX240
ospf3 {
traceoptions {
file debug-ospf size 1m files 5;
flag all;
}
export ospf3-default;
area 0.0.0.0 {
interface vlan.2;
interface lo0.0 {
passive;
}
interface ge-0/0/0.0 {
passive;
}
}
area 0.0.0.1 {
interface vlan.3;
}
}
EX3200
routing-instances {
VR1 {
protocols {
ospf3 {
area 0.0.0.0 {
interface vlan.2;
interface vlan.100 {
passive;
}
}
}
}
VR2 {
protocols {
ospf3 {
area 0.0.0.1 {
interface vlan.3;
interface vlan.160 {
passive;
}
}
}
}
}
Thank you in advance.
Best,
Junpei
