Interoperability Test Scenario :
Redirect : with RIPng

Last Update: November 22, 1999

This scenario verifies interoperability when the target ROUTER is attached to the model network. 

• Subjects:

   When the target router receives packets to be forwarded and it knows the better router
  to the destination address, it should transmit redirect message to the sender.

  Verification points:
      Whether the target ROUTER-1,2 transmits the Redirect Message to the sender.
      Whether the host can transmit packets to valid next-hop router after it receives
     Redirect Message from the target ROUTER-1,2.

• Physical Network Configuration:

                HOST-3
                   |
         -+--------+------------------(Net-x) (Prefix 3ffe:501:481d:f003::/64)
          |                                   (Prefix fec0:0:0:f003::/64)
          |(I/F-2x)
      ROUTER-2
          |(I/F-2y)
          |
         -+--------+-----------+------(Net-y) (Prefix 3ffe:501:481d:f002::/64)
                   |           |              (Prefix fec0:0:0:f002::/64)
                   |(I/F-1y)  HOST-2
               ROUTER-1
                   |(I/F-1z)
                   |
         ----------+-----------+------(Net-z) (Prefix 3ffe:501:481d:f001::/64)
                               |              (Prefix fec0:0:0:f001::/64)
                             HOST-1    

• Test Machine:

Machine	Comments	Initial status	Configuration
HOST-1	Reference Machine	Is attached to Net-z with power turned off.	-
ROUTER-1	Target Machine	Power is turned off. I/F-z is attached to Net-z while I/F-y is attached to Net-y.	Sends RIP to Net-z and Net-y. Sends RA to Net-z and Net-y.
HOST-2	Reference Machine	Is attached to Net-y with power turned off.	-
ROUTER-2	Target Machine	Power is turned off. I/F-y is attached to Net-y while I/F-x is attached to Net-x.	Sends RIP to Net-y and Net-x. Sends RA to Net-y and Net-x.
HOST-3	Reference Machine	Is attached to Net-x with power turned off.	-

• Applications

  Interoperability is checked using Ping6 application program.

  No	Action	Criteria	Comments
  1	Boot HOST-2.	-	HOST-2 should transmit NS for DAD (link-local/site-local/global) and MLDR/RS, and receive RA.
  2	Boot ROUTER-1.	-	ROUTER-1 should transmit NS for DAD (link-local/site-local/global) and RA/MLDR (AllRouter/RipRouter /OwnSolicietd/SubnetRouterSolicited).
  3	Boot ROUTER-2.	-	ROUTER-2 should transmit NS for DAD (link-local/site-local/global) and RA/MLDR (AllRouter/RipRouter /OwnSolicietd/SubnetRouterSolicited).
  4	Boot HOST-1.	-	HOST-1 should transmit NS for DAD (link-local/site-local/global) and MLDR/RS, and receive RA.
  5	Boot HOST-3.	-	HOST-3 should transmit NS for DAD (link-local/site-local/global) and MLDR/RS, and receive RA.
  6	At HOST-2, run "ping" to HOST-3's site-local address.	*HOST-2 sends ICMP Echo Request to HOST-3 (site-local). *HOST-2 receives ICMP Echo Reply from HOST-3 (site-local).	ROUTER-1 sends Redirect (if required).
  7	At HOST-2, run "ping" to HOTS-1's site-local address.	*HOST-2 sends ICMP Echo Request to HOST-1 (site-local). *HOST-2 receives ICMP Echo Reply from HOST-1 (site-local).	ROUTER-2 sends Redirect (if required).
  8	At HOST-2, run "ping" to HOST-3's global address.	*HOST-2 sends ICMP Echo Request to HOST-3 (global). *HOST-2 receives ICMP Echo Reply from HOST-3 (global).	ROUTER-1 sends Redirect (if required).
  9	At HOST-2, run "ping" to HOST-1's global address.	*HOST-2 sends ICMP Echo Request to HOST-3 (site-local). *HOST-2 receives ICMP Echo Reply from HOST-3 (global).	ROUTER-2 sends Redirect (if required).
