Feature Overview
The LCF Enhancements for Alternate Endpoints feature allows a Cisco IOS Gatekeeper (GK) to collect
additional routes to endpoints that are indicated by multiple LCF responses from remote GKs, and
convey a collection of those routes to the requesting (calling) endpoint. Currently, the originating GK
sends Location Request (LRQ) messages to multiple remote zones. Remote GKs in the zones return LCF
responses to the originating GK. The LCF responses indicate alternate routes to the remote GK’s
endpoints. The consolidation of LCF responses to multiple LRQs can provide many alternate routes to
reach a given destination. An endpoint can have up to 20 alternate endpoints.
