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.
Scenario
Step 1: Set the following configuration in DUT1 :

Step 7: Run the command system journal show | tail on DUT0 and check whether the output contains the following tokens:
PREC=0x20Show output

Step 8: Run the command system journal clear on DUT0 and expect the following output:
Show output
Vacuuming done, freed 0B of archived journals from /run/log/journal. Vacuuming done, freed 0B of archived journals from /var/log/journal. Deleted archived journal /run/log/journal/3a8dbab828fc40a183893e468c03e10b/system@f6b627f530614ebebcf2fb35acc78ad6-000000000000687a-000657571db948f2.journal (84.0K). Vacuuming done, freed 84.0K of archived journals from /run/log/journal/3a8dbab828fc40a183893e468c03e10b.
Step 9: Modify the following configuration lines in DUT0 :
set protocols bfd profile BFD_TOS tos 184
Step 10: Run the command system journal show | tail on DUT0 and check whether the output contains the following tokens:
