Bfd Tos
Scenario to verify BFD ToS (Type of Service) functionality with BGP. BFD profile tos allows setting the IP ToS field on BFD packets. By default BFD uses CS6 (0xC0). These tests verify that the ToS is applied correctly, can be changed dynamically, and is visible in the actual packets via system journal.
Test BFD Profile ToS
Description
Test that BFD profile tos is applied correctly. Configures a BFD profile with tos 48 on both routers and verifies that BGP establishes, BFD is up with the correct ToS value, and end-to-end connectivity works.

Step 8: Run command system journal clear at DUT0 and expect this output:
Show output

Step 9: Modify the following configuration lines in DUT0 :
set protocols bfd profile BFD_TOS tos 184
Step 10: Run command system journal show | tail at DUT0 and check if output contains the following tokens:
