Send packets to DUT port-1. The outer v4 header has the destination addresses 138.0.11.8. Validate that:
- All egress packets (100%) are IPinIP (4in4) encapped.
- Packets are encapped to the tunnel IPs in the specified ratio. Specifically, 25% of the egress packets should have the destination address 203.0.113.1, and 75% of the egress packets should have the destination address 203.10.113.2.
- The encapped/tunneled packets should be distributed hierarchically per the weight.
- The DSCP value is copied from the inner header to the outer header.
- The TTL value is copied from the inner header to the outer header.
Send packets to DUT port-1. The outer v6 header has the destination addresses 2015:aa8::1. Validate that:
- All egress packets (100%) are 6in4 encapped.
- Packets are encapped to the tunnel IPs in the specified ratio. Specifically, 25% of the egress packets should have the destination address 203.0.113.1, and 75% of the egress packets should have the destination address 203.10.113.2.
- The encapped/tunneled packets should be distributed hierarchically per the weight.
- The DSCP value is copied from the inner header to the outer header.
- The TTL value is copied from the inner header to the outer header.
Tests support for encap of IPinIP IPv4 (IP protocol 4) traffic. Specifically, in
this test we’ll focus on tunnel traffic identification using
ipv4_outer_src_111``andipv4_outer_src_222``.
- Send 4in4 (IP protocol 4) and 6in4 (IP protocol 41) packets to DUT port-1.
- The outer v4 header has the destination address 138.0.11.8.
- The outer v4 header has the source address that’s not
ipv4_outer_src_111``oripv4_outer_src_222``. For example, we can use 198.100.200.123. - The outer v4 header should have DSCP value
dscp_encap_a_1.
- Validate that:
- All egress packets (100%) are IPinIP (4in4) encapped.
- Packets are encapped to the tunnel IPs in the specified ratio. Specifically, 25% of the egress packets should have the destination address 203.0.113.1, and 75% of the egress packets should have the destination address 203.10.113.2.
- The encapped/tunneled packets should be distributed hierarchically per the weight.
- The DSCP value is copied from the inner header to the outer header.
- The TTL value is copied from the inner header to the outer header.
