NAME

  Test v6LC.1.1.11 -  IP Forwarding - Routing prefixes greater than 64 bits (Routers Only)
  Part A - Prefix Route /65


Purpose

  Verify that a router properly routes prefixes greater than 64-bits.


References

  * [RFC-7608]  Sections 2


Resource Requirements

  * Packet generator
  * Monitor to capture packets


Test Setup

  The Common Test Cleanup Procedure is performed after each part.


Procedure


   1. Configure the RUT to have a route with a prefix length of /65 for Link C with a next-hop 
      router of TR2. A default route should be configured to TR1.
   2. TN4 has an address which matches the /65 prefix for Link C for the first 64 bits.
   3. TN2 transmits an ICMPv6 Echo Request to TN4's address with a first hop through the RUT. 
      The source address is TN2's Global address. 
   4. TN4 has an address in the /65 prefix for Link C.
   5. TN2 transmits an ICMPv6 Echo Request to TN4's address with a first hop through the RUT. 
      The source address is TN2's Global address. 
   6. TN4 has an address in the /65 prefix for Link C and has the 66th bit set to 1.
   7. TN2 transmits an ICMPv6 Echo Request to TN4's address with a first hop through the RUT. 
      The source address is TN2's Global address.


Observable Results

  Step 3:
  The RUT must forward the Echo Request to TR1. The destination MAC address must be TR1's MAC address.
  Step 5:
  The RUT must forward the Echo Request to TR1. The destination MAC address must be TR2's MAC address.
  Step 7:
  The RUT must forward the Echo Request to TR1. The destination MAC address must be TR2's MAC address.


Possible Problems

  * None.
