Ethernet Connectivity Fault Management
Overview
RBFS supports Connectivity Fault Management (CFM) that functions as an Ethernet layer Operations, Administration, and Maintenance (OAM) protocol. This feature enables connectivity monitoring, fault verification, and isolation, thereby ensuring network reliability.
CFM is used to detect, verify, and isolate connectivity issues within Ethernet networks. It operates over Ethernet, and utilizes Ethernet frames for communication.
| RBFS OAM supports both point-to-point and point-to-multipoint CFM sessions. |
Nexthop Tracking
RBFS supports nexthop tracking for Layer 2 issues using CFM (Connectivity Fault Management) sessions. It tracks the reachability of nexthop devices on a network path when CFM is enabled. The functionality enables detection of routing failures by continuously monitoring the availability and responsiveness of nexthop nodes.
| CFM next-hop tracking is not supported for MPLS, VPN, IPv4 and IPv6 labeled unicast address families. |
