NAME

  Test v6LC.2.2.7 - Sending Unsolicited Router Advertisements (Routers Only)
  Part A: Sending Unsolicited RA (MinRtrAdvInterval <= interval <= MaxRtrAdvInterval)

Purpose

  Verify that a router sends the first few advertisements (up to
  MAX_INITIAL_RTR_ADVERTISEMENTS) from an interface when it becomes an advertising interface
  at an maximum interval value of MAX_INITIAL_RTR_ADVERT_INTERVAL (16) seconds. Verify that
  a router transmits valid router advertisements.

Resource Requirements

  * Packet generator
  * Monitor to capture packets

Test Setup

  No Common Test Setup is performed. The Common Test Cleanup procedure is
  performed after each part.

Procedure

  Part A: Sending Unsolicited RA (MinRtrAdvInterval <= interval <= MaxRtrAdvInterval)
   1. Configure Interface A on the RUT to be an advertising interface with a MinRtrAdvInterval of 5
      seconds and a MaxRtrInterval of 10 seconds.
   2. Observe the packets transmitted by the RUT on Interface A.

Observable Results

  Part A
    Step 2:
    The RUT transmits the consecutive Router Advertisements at randomly chosen intervals between the
    interface's configured MinRtrAdvInterval (5) and MaxRtrAdvInterval (10) seconds, and it
    MUST NOT transmit Router Advertisements more frequently than indicated by
    MinRtrAdvInterval (5) seconds.

Possible Problems

  * None.
