TE-14.2: encap and decap scale

Summary

Introduce encapsulation and decapsulation scale test on top of TE-14.1

Topology

Use the same topology as TE-14.1

Variables

# DSCP value that will be matched to ENCAP_TE_VRF_A
* dscp_encap_a_1 = 10
* dscp_encap_a_2 = 18

# DSCP value that will be matched to ENCAP_TE_VRF_B
* dscp_encap_b_1 = 20
* dscp_encap_b_2 = 28

# DSCP value that will be matched to ENCAP_TE_VRF_C
* dscp_encap_c_1 = 30
* dscp_encap_c_2 = 38

# DSCP value that will be matched to ENCAP_TE_VRF_D
* dscp_encap_d_1 = 40
* dscp_encap_d_2 = 48

# Magic source IP addresses used in VRF selection policy
* ipv4_outer_src_111 = 198.51.100.111
* ipv4_outer_src_222 = 198.51.100.222

# Magic destination MAC address
* magic_mac = 02:00:00:00:00:01

Baseline

  1. Build the same scale setup as TE-14.1.
  2. Apply vrf_selection_policy_w to DUT port-1.

Procedure

  1. via gRIBI installs the following AFT entries:

    • Add 4 VRFs for encapsulations: ENCAP_TE_VRF_A, ENCAP_TE_VRF_B, ENCAP_TE_VRF_C and ENCAP_TE_VRF_D.
    • Add 1 VRF for decapsulation, DECAP_TE_VRF.
    • Add 2 Tunnel VRFs, TE_VRF_111 and TE_VRF_222.
    • Inject 5000 IPv4Entry-ies and 5000 IPv6Entry-ies to each of the 4 encap VRFs.
    • The entries in the encap VRFs should point to NextHopGroups in the DEFAULT VRF. Inject 800 such NextHopGroups in the DEFAULT VRF.
    • Each NextHopGroup should have 8 NextHops where each NextHop points to a tunnel in the TE_VRF_111. In addition, the weights specified in the NextHopGroup should be co-prime and the sum of the weights should be 16.
    • Inject 48 entries in the DECAP_TE_VRF where the entries have a mix of prefix lengths /22, /24, /26, and /28.

  2. Send the following packets to DUT-1

    * inner_src: `ipv4_inner_src`
* inner_dst: `ipv4_inner_encap_match`

* outer_dst: `ipv4_outer_decap_match`
* dscp: `dscp_encap_d`
* proto: `41`

  3. Send traffic to DUT-1, covering all the installed v4 and v6 entries in the decap and encap VRFs. Validate that all traffic are all decapped per the DECAP VRFs and then encapsulated per the ENCAP VRFs and received as encapsulated packet by ATE.

  4. Flush the DECAP_TE_VRF, install 5000 entries with fixed prefix length of /32, and repeat the same traffic validation.
