Redirect with RIPng

[Interoperability Test Scenario]

Last Update: February 26, 2000

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 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.
  

• 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

Network	Prefix	Network media

• Test Machines:

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

• Detect Protocols:

  ICMP

• Applications:

  ping program (ping)

• Interoperability Check:

  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).
