Version 2.3.4 of ImageStream's Enterprise Linux is now available as a general release for all ImageStream router customers. Version 2.3.4 is a maintenance release. This software release is provided at no charge to all ImageStream customers, and is recommended for all customers who wish to upgrade to the latest available software release. This release note documents commands and features added between Version 2.3.3 and Version 2.3.4. ---------------------------- New Features in Version 2.3.4 SAND Version Updated The recently-announced Version 3.30 of SAND is included in Version 2.3.4. GateD Dynamic Routing Package Updated The GateD dynamic routing program has been updated for Version 3.0. The interactive interface to gated, gii, now is only available on through a direct connection on the router (localhost) and ipchains/iptables rules are not required to block outside access. The "show bgp summary" and "show bgp peeras <AS number>" commands now also reflect the number of route announcements sent to and received from each peer. ---------------------------- Bugs fixed in Version 2.3.4 The following bugs have been fixed in Version 2.3.4: Workaround For Cisco IOS Bug in BGP Added to GateD Certain versions of the Cisco IOS accept and propagate invalid routing information. This behavior is in violation of the BGP RFC, and causes RFC-compliant devices, including ImageStream routers, to properly drop peering sessions. When affected Cisco routers are upstream of an RFC-compliant device, this can cause a loss of connectivity for the downstream router. ImageStream has patched GateD to log an error and ignore invalid route announcements in these situations. Peering sessions will no longer be automatically terminated. Gated Display Of "checkconf" Output At Boottime Requiring User Intervention Gated no longer displays the output of the "checkconf" command at boottime. Previously, incorrect configurations could cause the router to require user input at the console to continue the boot process. Beginning with Version 3.0-beta2, the checkconf output is no longer displayed at boottime. ---------------------------- Upgrade Instructions *** NOTE! If the upgrade fails, do NOT reboot! Contact ImageStream's Technical Support without rebooting. *** The upgrade process on an ImageStream router erases the operating system software area from nonvolatile memory. Never interrupt the upgrade process, or loss of software information can result. The upgrade does not otherwise affect the stored configuration in the ImageStream router. To back up the router's configuration prior to upgrading, choose option 4 (Backup/Restore) from the router's main menu. Choose the Backup methods option (Option 1) and select a method from the choices listed. From the router's command line, use the "backup <typeofbackup>" command. The backup utility takes four arguments: flash (to back up configurations to the router's nonvolatile flash memory), floppy (to back up to a floppy disk), scp (to back up via secure copy), or file (to back up to a separate file on the router's nonvolatile flash memory). ---------------------------- Copyright and Trademarks Copyright 2001 ImageStream Internet Solutions.
