IPv4 Test Case

config_fib_entries(count)

For each interface add to the FIB table count routes to “10.0.0.1/32” destination with interface’s local address as next-hop address.

Parameters:count (int) – Number of FIB entries.

• TODO: check if the next-hop address shouldn’t be remote address instead of local address.

create_stream(src_if, packet_sizes)

Create input packet stream for defined interface.

Parameters:

• src_if (VppInterface) – Interface to create packet stream for.
• packet_sizes (list) – Required packet sizes.

setUp()

Perform test setup before test case.

Config:

• create 3 pg interfaces

  • untagged pg0 interface
  • Dot1Q subinterface on pg1
  • Dot1AD subinterface on pg2

• setup interfaces:

  • put it into UP state
  • set IPv4 addresses
  • resolve neighbor address using ARP

• configure 200 fib entries

Variables:

• interfaces (list) – pg interfaces and subinterfaces.
• flows (dict) – IPv4 packet flows in test.
• pg_if_packet_sizes (list) – packet sizes in test.

tearDown()

Run standard test teardown and log show ip arp.

test_fib()

IPv4 FIB test

Test scenario:

• Create IPv4 stream for pg0 interface
• Create IPv4 tagged streams for pg1’s and pg2’s subinterface.
• Send and verify received packets on each interface.

verify_capture(dst_if, capture)

Verify captured input packet stream for defined interface.

Parameters:

• dst_if (VppInterface) – Interface to verify captured packet stream for.
• capture (list) – Captured packet stream.

class test_ip4.TestIPv4FibCrud(methodName='runTest')

Bases: framework.VppTestCase

FIB - add/update/delete - ip4 routes

Test scenario:

• add 1k,
• del 100,
• add new 1k,
• del 1.5k

..note:: Python API is too slow to add many routes, needs replacement.

config_fib_many_to_one(start_dest_addr, next_hop_addr, count)

Parameters:

• start_dest_addr –
• next_hop_addr –
• count –

Return list:

added ips with 32 prefix

create_stream(src_if, dst_if, dst_ips, count)

setUp()

classmethod setUpClass()

1. Create and initialize 3 pg interfaces.
2. initialize class attributes configured_routes and deleted_routes to store information between tests.

test_1_add_routes()

Add 1k routes

• add 100 routes check with traffic script.

test_2_del_routes()

Delete 100 routes

• delete 10 routes check with traffic script.

test_3_add_new_routes()

Add 1k routes

• re-add 5 routes check with traffic script.
• add 100 routes check with traffic script.

test_4_del_routes()

Delete 1.5k routes

• delete 5 routes check with traffic script.
• add 100 routes check with traffic script.
