| Documentation | *IPv4 routing with ingress ACL test cases*
| ...
| ... | Encapsulations: Eth-IPv4 on links TG-DUT1, TG-DUT2, DUT1-DUT2. IPv4
| ... | ingress ACL (iACL) tests use 3-node topology TG - DUT1 - DUT2 - TG with
| ... | one link between the nodes. DUT1 and DUT2 are configured with IPv4
| ... | routing and static routes. DUT1 is configured with iACL on link to TG,
| ... | iACL classification and permit action are configured on a per test
| ... | case basis. Test ICMPv4 Echo Request packets are sent in one direction
| ... | by TG on link to DUT1 and received on TG link to DUT2. On receive TG
| ... | verifies if packets are accepted, or if received verifies packet IPv4
| ... | src-addr, dst-addr and MAC addresses.
