Hi kennethgoh,
I was trying to load your configuration on one of my decvices and I can see the below error which is expected.
root@SRX# commit
[edit security zones security-zone untrust]
'interfaces lo0.0'
Interface lo0.0 must be in the same routing instance as other interfaces in the zone
error: configuration check-out failed
Looks like the configuration is not commit. Can you provide configuration output from operational mode
"root>show configuration|no-more"
We cannot have interfaces in different routing instances part of same security zones.
In your case lo0 is part of routing instance TRUST but its placed under zone TRUST which contains interface fe-0/0/0 which is not part of routing instance TRUST.
Thanks,
Suraj
