Configuring Interface and Router Redundancy

Redundancy services enable a router to recover from either interface or router failure with minimal

delay.

• Interface redundancy protects your network from failures of individual LAN interfaces by

backing up one interface with another interface on the same router.

• Router redundancy protects a network from the irrecoverable failure of an entire router. You

configure routers to be members of a router redundancy group, which includes a primary

router and one or more secondary routers that take over if the primary router fails.

This manual describes how to configure interface and router redundancy services on a Nortel

Networks router.

Configuring Traffic Filters and Protocol Prioritization

Traffic filters manage customer traffic and reduce network congestion. Inbound traffic filters can

restrict access to nodes in a network.

Outbound traffic filters ensure timely delivery of critical data,

or restrict traffic leaving the network.

Protocol prioritization enables the router to sort traffic into priority queues (high, normal, and low).

Protocol prioritization is an outbound traffic filter mechanism that affects the sequence in which

data leaves an interface; it does not affect traffic as it arrives at the router.

This manual describes how to configure traffic filters and prioritize traffic on a Nortel Networks

router.
