AFT-1.1: AFTs Base

Summary

IPv4/IPv6 unicast routes next hop group and next hop.

Testbed

  • atedut_2.testbed

Test Setup

Generate DUT and ATE Configuration

Configure DUT:port1,port2 for IS-IS session with ATE:port1,port2.

  • Let X be the number of IPv4 prefixes to be advertised by eBGP. (User Adjustable Value)
  • Let Y be the number of IPv6 prefixes to be advertised by eBGP. (User Adjustable Value)
  • Let Z be the number of prefixes to be advertised by IS-IS. (User Adjustable Value)
  • IS-IS must be level 2 only with wide metric.
  • IS-IS must be point to point.
  • Send Z IPv4 and Z IPv6 prefixes from ATE:port1 to DUT:port1.

Establish eBGP multipath sessions between ATE:port1,port2 and DUT:port1,port2

  • Configure eBGP over the interface IP between ATE:port1,port2 and DUT:port1,port2.
  • Advertise X IPv4 and Y IPv6 prefixes from ATE port1,port2.
  • Each prefix advertised by eBGP must have 2 next hops pointing to ATE port1 and ATE port2.
  • Each prefix advertised by ISIS must have one next hop pointing to ATE port1.

Procedure

  • Use gNMI.UPDATE option to push the Test Setup configuration to the DUT.
  • ATE configuration must be pushed.

Verifications

  • eBGP routes advertised from ATE:port1,port2 must have 2 nexthops.
  • Use gNMI Subscribe with ON_CHANGE option to /network-instances/network-instance/afts.
  • Verify AFTs prefixes advertised by eBGP and ISIS.
  • Verify their next hop group, number of next hops, and the name of the interfaces.
  • Verify the number of next hops is 2 for eBGP advertised prefixes.
  • Verify the number of next hop is 1 for ISIS advertised prefixes.
  • Verify the prefixes are pointing to the correct egress interface(s).
  • Verify all other leaves mentioned in the path section have the data populated correctly.

AFT-1.1.1: AFT Base Link Down scenario 1

Procedure

Bring down the link between ATE:port2 and DUT:port2 using OTG API.

Verifications

  • eBGP routes advertised from ATE:port1,port2 must have 1 nexthop (pointing to ATE:port1).
  • IS-IS routes advertised from ATE:port1 must have one next hop.
  • Verify AFTs prefixes advertised by eBGP and ISIS.
  • Verify their next hop group, number of next hops, and the name of the interfaces.
  • Verify the number of next hop per prefix must be 1.

AFT-1.1.2: AFT Base Link Down scenario 2

Procedure

Bring down both links between ATE:port1,port2 and DUT:port1,port2 using OTG API.

Verifications

  • eBGP routes advertised from ATE:port1,port2 must be removed from RIB and FIB of the DUT (query results should be nil).
  • ISIS routes advertised from ATE:port1 must be removed from RIB and FIB of the DUT (query result should be nil).

AFT-1.1.3: AFT Base Link Up scenario 3

Procedure

Bring up the link between ATE:port1 and DUT:port1 using OTG API.

Verifications

  • eBGP routes advertised from ATE:port1,port2 must have one next hop (pointing to ATE:port1).
  • IS-IS routes advertised from ATE:port1 must have one next hop.
  • Verify AFTs prefixes advertised by eBGP and ISIS.
  • Verify their next hop group, number of next hops, and the name of the interfaces.
  • Verify the number of next hop per prefix is 1.

AFT-1.1.4: AFT Base Link Up scenario 4

Procedure

Bring up both links between ATE:port1,port2 and DUT:port1,port2 using OTG API.

Verifications

  • eBGP routes advertised from ATE:port1,port2 must have 2 next hops.
  • IS-IS routes advertised from ATE:port1 must have one next hop.
  • Verify AFTs prefixes advertised by eBGP and ISIS.
  • Verify their next hop group, number of next hops, and the name of the interfaces.
