[j-nsp] STM-1 & IP Option "Flags: Dest-route-down"

[Alex Kitschkiruk]

Hi!
I have M20 with STM-1 SONET card & 4Ports FE. I cannot send from M20
ping command.
In the interface so-1/2/3 is error alarm:
Flags: Dest-route-down
what means that? how can I change that? how can I routing from SONET to FE?
