Redundancy Features Overview
The CTP series provides the following redundancy features:
- Ethernet interface failover—If the default Ethernet interface fails, the CTP device fails over to the next unconfigured Ethernet interface.
- Route management redundancy—If the next-hop gateway (the router) becomes unreachable, the CTP device uses configured static routes to a next-hop gateway on a different network.
- Bundle failover between CTP devices at alternate sites—If a bundle circuit fails and the CTP device becomes unreachable, the CTP device fails over to a CTP device at an alternate site.
- Bundle failover between CTP devices at the same site—If a bundle circuit fails and the CTP device becomes unreachable, the CTP device fails over to a redundant CTP device that is connected to the failed device by a Y cable.
- Packet redundancy—If packets are lost because of transmission errors, the packet protector feature can enable a possible recovery scenario.
