Symptom
When BOW is configured and tunnels dont meet SLA then we are ignoring primary color preference but secondary and teritary are considered from TT pref configuration.
BOW should honor the configuration from TT pref.
Example:
3 color : Gold , LTE and custom1
TT config:
Primary: Gold
Secondary: LTE
Tertiary: Custom1
BOW is considered and none of tunnels meet SLA.
Gold, LTE are BOW but Gold is ignored and only LTE is considered for sending traffic,
Conditions
BOW with Tiered Transport perference configuration. No tunnel meets the SLA criteria and strict check is not applicable. Will be seen in all platforms.
