Hi Spluka,
Yes adding the options for 'source-adress' and 'routing-instance' does help my problem with certain configuration like radius and etc.
But i cant seeem to get it working with NTP, and archival-site with FTP.
All i would want is to be able to configure a new MGMT vlan which uses it IP as default source adress, it must be possible to overwrite the routing-instance/lo0?
For instance, if i configure a vlan/irb with a low unit number it outranks the default 101 vlan and since there is no lo0 configured it works, and i dont understand why it doesnt work as is with the ISP loopback adress which has been given to us and is the router ID. the lo0 interface is in the inet.0 but if i write following "ping <HOST> source 10.99.99.40 it cant assign the adress, if i specify the routing-instance with the IP 10.99.99.40 as the router-id it works "ping <HOST> routing-instance 901>"
