2.36. test_ipsec_esp module

class test_ipsec_esp.TestIpsecEsp(methodName='runTest')

Bases: framework.VppTestCase

Basic test for ipsec esp sanity - tunnel and transport modes.

Below 4 cases are covered as part of this test 1) ipsec esp v4 transport basic test - IPv4 Transport mode

scenario using HMAC-SHA1-96 intergrity algo

2. ipsec esp v4 transport burst test

   Above test for 257 pkts

3. ipsec esp 4o4 tunnel basic test - IPv4 Tunnel mode

   scenario using HMAC-SHA1-96 intergrity algo

4. ipsec esp 4o4 tunnel burst test

   Above test for 257 pkts

TRANSPORT MODE:

— encrypt —

|pg2| <——-> |VPP|

— decrypt —

TUNNEL MODE:

— encrypt — plain —

|pg0| ——-> |VPP| ——> |pg1|

— — —

— decrypt — plain —

|pg0| <——- |VPP| <—— |pg1|

— — —

Note : IPv6 is not covered
