Summary

This test validates the support for AIGP ensuring the following use-cases

  1. The attribute can be transmitted and received between two bgp peers
  2. The propagation of the attribute can be controlled both per bgp neighbor and peer-group
  3. The attribute can be modified as needed with a policy on both import and export direction on a BGP peer

RT-1.36.4 : Validate the Plus 1 incremental feature of AIGP when the IGP metric to original destination is zero

The following configuration steps are additions to the configuration done on Test-case RT-1.36.3 above.

DUT 1 - Generate Configuration

ISIS Configuration - Default Network instance

  • Configure a ISIS metric of Zero on Lag 2 vlan 10 and lag 2 vlan 30 for both IPV4 and IPV6 address-family

ISIS Configuration - test-instance Network instance

  • Configure a ISIS metric of Zero on Lag 2 vlan 20 and lag 2 vlan 40 for both IPV4 and IPV6 address-family

DUT 2 - Generate Configuration

ISIS Configuration - Default Network instance
  • Configure a ISIS metric of Zero on Lag 2 vlan 10 for both IPV4 and IPV6 address-family
ISIS Configuration - test-instance Network instance
  • Configure a ISIS metric of Zero on Lag 2 vlan 20 for both IPV4 and IPV6 address-family
ISIS Configuration - test-originate Network instance
  • Configure a ISIS metric of Zero on lag 2 vlan 30 and vlan 40 for both IPV4 and IPV6 address-family

Testing Steps

ISIS testing step on DUT 1
  • In the DEFAULT network instance, fetch the ISIS metric on interfaces Lag 2 vlan 10 and lag 2 vlan 30
  • In test-instance Network instance, fetch the ISIS metric on Lag 2 vlan 20 and lag 2 vlan 40
ISIS testing step on DUT 2
  • In the DEFAULT network instance,fetch the ISIS metric on Lag 2 vlan 10
  • In test-instance Network instance,fetch the ISIS metric on Lag 2 vlan 20
