Hi all,

Has anyone found problems using default-address-selection enabled, and
passing traffic across an T3 interface ?

These results show 'das' disabled, and then a rapid ping, 'das' enabled and
then a rapid ping, and then with an added source-address of the local
interface.

It seems that a problem exists between the physical interface (T3) and the
pfe.
