Configuring Interface and Router Redundancy

3-2 114079 Rev. A

b. Each member ID must be unique within the group. Role-changing rules

use the member IDs to reassign roles. When two routers have the same

priority, the one with the lowest member ID becomes the primary router

when a role change occurs.

3. Use more than one interface as the backup interface for router redundancy.

This procedure avoids a single point of failure.

Refer to Appendix C for worksheets to help you plan your router redundancy

group.

Protocols Supported

Interface and router redundancy work with IP, IPX, Spanning Tree Bridging, and

Source Route Bridging. Interface redundancy also works with AppleTalk and

VINES.

LAN Interfaces

Interface and router redundancy support the following LAN interfaces as

redundant interfaces: 10-Mb Ethernet, 100-Mb Ethernet, Token Ring, and FDDI.

All members of an interface redundancy group must be LAN interfaces of the

same type.

Multiple LAN interfaces of the same type or different types can carry the router

redundancy protocol.

Router Redundancy Requirements

All members of a router redundancy group must

• Be the same router type; for example, BCN

, BLN

, or ASN™.

• Have the same hardware conﬁguration. This includes CPU and interface

module types, and slot and port locations of the backed-up interfaces.

• Have the same software conﬁguration. For example, you must be running the

same router software version and have the same loadable modules conﬁgured.
