This test ensures NOS is able to host multiple VRFs and at the same time perform GUE tunnel DECAP in the default VRF

Test environment setup

Create the following connections:

graph LR; 

A[ATE:Port1] <--IBGP(ASN100)--> B[Port1:DUT:Port2];B <--EBGP(ASN100:ASN200)--> C[Port2:ATE];

• DUT has 2 VRFs, Default and Non-Default.
• DUT:Port1 and DUT:Port2 are in the Default VRF.
• BGP sessions between ATE:Port1 <> DUT:Port1 and ATE:PORT2 <> DUT:PORT2 are in Default VRF.
• Ensure leaking routes from the default to the non-default VRFs so prefixes learnt over IBGP and EBGP are available in the tables of both VRFs.There are no other routes learned into non-Default VRF.
• Ensure IPv4Prefix12/28 is configured on the Loopback0 interface of DUT which is also in the Default VRF
• Loopback0:IPv4Prefix12/28 is used as target address for GUE decapsulation on DUT
• Ensure the DUT has accurate QOS classifier configured on DUT:PORT1 and and DUT:PORT2 ports, with DSCP and traffic-class mapping called out in section "Traffic-Class to DSCP mapping".

• DUT has 2 VRFs, Default and Non-Default(say B2_VRF).
• Establish BGP sessions as shown in the DUT configuration section
• ATE1 advertises routes shown in "ATE Route Advertisements" section
• ATE2 advertises routes shown in "ATE Route Advertisements" section
• Configure ATE with Flow-types mentioned in "Packet types and Flow-types"

• Start above flow-type 1to6v4 - 5to10v4 and 1to6v6 - 5to10v6 between ATE:Port1 and ATE:Port2.
• Ensure no packet loss is observed
  
  
  

• ATE:Port1 sends flow-type 1to6v4_encapped and 1to6v6_encapped
• DUT will perform the decapsulation in Default VRF
• ATE:Port1 continues to send the following IPv4 and IPv6 flows
  • 2to7v4 - 5to10v4
  • 2to7v4 - 5to10v6
• DUT receives the tunneled traffic for flow-type 1to6v4_encapped and 1to6v6_encapped, decaps it, does a LPM lookup on the destination prefix (IPv4Prefix6 and IPv6Prefix6) and routes it to ATE:Port2 via DUT:Port2
• All the traffic flows MUST show no packet loss.
• Streamed data on the number of packets decaped by the Tunnel endpoint "IPv4Prefix12" must match the number of tunnel encaped packets sent by ATE:Port1 for 1to6v4_encapped and 1to6v6_encapped flows .

• DUT will perform the decapsulation in Default VRF
• DUT receives the tunneled traffic for flow-type 1to6v4_encapped - 2to74_encapped, 1to6v6_encapped - 2to7v6_encapped, decaps it, does a LPM lookup on the destination prefix (IPv4Prefix6, IPv4Prefix7, IPv6Prefix6, IPv6Prefix7) and routes it to ATE:Port2 via DUT:Port2
• All the traffic flows MUST show no packet loss.
