Redirect Host behavior

[Interoperability Test Scenario]

Last Update: February 26, 2000

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

• Subjects:

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

  Verify the behavior when the target HOST receives a Redirect message:
  

  Whether the 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 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
Net-x	3ffe:501:481d:f003::/64 fec0:0:0:f003::/64	Ethernet 10BASE-T
Net-y	3ffe:501:481d:f002::/64 fec0:0:0:f002::/64	Ethernet 10BASE-T
Net-z	3ffe:501:481d:f001::/64 fec0:0:0:f001::/64	Ethernet 10BASE-T

• Test Machine:

Machine	Comments	Initial status	Configuration
HOST-1	Reference Machine	Is attached to Net-z with power turned off.	-
ROUTER-1	Reference Machine	Power is turned off. I/F-z is attached to Net-z while I/F-y is attached to Net-y.	Sends RA to Net-z and Net-y. Doesn't send and receive RIP.
HOST-2	Your Machine	Is attached to Net-y with power turned off.	-
ROUTER-2	Reference Machine	Power is turned off. I/F-y is attached to Net-y while I/F-x is attached to Net-x.	Sends RA to Net-y and Net-x.. Doesn't send and receive RIP.
HOST-3	Reference Machine	Is attached to Net-x with power turned off.	-

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).	HOST-2 receives Redirect (if required). Both HOSTS select site-local address as Source Address.
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).	HOST-2 receives Redirect (if required). Both HOSTS select site-local address as Source Address.
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).	HOST-2 receives Redirect (if required). Both HOSTS select global address as Source Address.
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).	HOST-2 receives Redirect (if required). Both HOSTS select global address as Source Address.
