Vnet_route_check Vxlan tunnel route update. by siqbal1986 · Pull Request #2281 · sonic-net/sonic-utilities

siqbal1986 · 2022-07-31T22:05:31Z

Modified Vnet_route_check to ignore the Vxlan tunnel routes which uses default VRF.

What I did

Updated the vnet_route_check script to handle the vxlan tunnel routes.

How I did it

By checking the scope of the tunnel route, if it is default then it is treated in a different way. Tunnel routes coming from App_db are compared with ASIC_db default_VRF routes and their presence is verified.
For routes coming from ASIC_db with default_VRF, the comparison is not done with the routes form App_db as ASIC_DB carries all other the routes.
For normal vnet routes, the functionality of the script is unaffected.

How to verify it

run the script after adding a vxlan tunnel.

We should not ignore vnet routes in the script. Scrip must handle the vnet routes in default scope and proceed with the check

can you please add some tests and also fix the test failure?

scripts/vnet_route_check.py

+            if vnet_name not in vnet_intfs:
+                # this route has no vnet_intf and may be part of default VRF.
+                vnet_table = swsscommon.Table(db, 'VNET_TABLE')
+                scope = vnet_table.get(vnet_name)[1][1][1]


what is this index [1][1][1] ? Can you provide an example?

this looking up the scope=default but i think I can improve it.

scripts/vnet_route_check.py

    vnet_intfs = get_vnet_intfs()

    vrf_oid_to_vnet_map = {}
+    vrf_oid_to_vnet_map[default_vrf_oid] = 'default_VRF'


I don't see this being used. Can you confirm?

This is used as a placeholder, as the data structure keeps track of the routes by means of the vnet interface.

scripts/vnet_route_check.py

+    virtual_router = swsscommon.Table(asic_db, 'ASIC_STATE:SAI_OBJECT_TYPE_VIRTUAL_ROUTER')
+    default_vrf_oid = ""
+    if virtual_router.getKeys() != []:
+        default_vrf_oid = virtual_router.getKeys()[0]


please make it as a global variable so you don't have to pass it in multiple places and use as "self.xxx"
