LOCAL FIX: PROBLEM SUMMARY: **************************************************************** * USERS AFFECTED: All users of MPRoute * **************************************************************** * PROBLEM DESCRIPTION: When an LCS or OSD device is started * * with OBEYFILE, MPRoute does not join * * the multicast group 224.0.0.5. * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** When a device is started using OBEYFILE, the TCP/IP stack sends information to MPRoute indicating that the device is now up. Since the information is sent before OSD or LCS devices determine if they support multicast, it indicates that these devices do NOT support multicast. Thus MPRoute does not join the routing multicast group 224.0.0.5. PROBLEM CONCLUSION: The device drivers for LCS and OSD have changed so that the MPRoute information is sent after the multicast support has been determined.
