Improved Management Routing The following improvements have been made to management routing Route advertisement over LAN interface the surface mechanism OSPF eliminates the need to add to static route tables in an affiliate router when a Cisco ONS ring is deployed Only the node IP address is sent to external systems via OSPF IP addresses on cards are not sent You can configure OSPF so that node IPs are not sent The default configuration is off not advertising OSPF Craft attachment Craft attachment and management of all nodes on a DCC regardless of subnetting without the addition of static routes to the craft PC is now possible Automatic Host Detection and Proxy Server are supported to provide this capability Multiple craft attachments to the same DCC can occur at the same time Route learning and aging support redundant physical connections to an ONS 15327 ring are supported including rerouting messages through an alternate route and or an alternate ONS 15327 gateway Nodes can reroute messages including the primary and secondary gateway nodes This feature is not affected by subnet configuration all nodes on one subnet all nodes on different subnets or any combination Release Notes for Cisco ONS 15327 Release 3 3 P24 g OL 2671 01 New Features and Functionality i Improved GUI on Circuit Creation Wizard A panel was added to the Circuit Creation Wizard to record entries from previous pages This panel
