Getting Started

In This Chapter

This chapter provides process flow information to configure dynamic IP routing protocols.

The 7705 SAR router can function as an LSR (label switch router), allowing it to be used in more complex networks; for example:

  1. tier-2 aggregation (aggregator of aggregator sites) – traffic is aggregated from other tier-3 7705 SAR nodes (aggregated small cell sites), and this traffic, along with local traffic, is switched to tier-1 SR nodes
  2. ring-based configurations – multiple tier-3/tier-2 7705 SAR nodes are linked via a ring and an SR tier-2/tier-1 node, which acts as a gateway from the ring to a higher level or directly to the MTSO
    Note:

    For information on the 7705 SAR as an LSR, refer to the 7705 SAR OS MPLS Guide.

To switch traffic from one router to another in the network, the 7705 SAR must support IP forwarding. To support these larger and more complex topologies, dynamic routing protocols are provided. The 7705 SAR supports OSPF, IS-IS, BGP, and RIP as dynamic routing protocols.

Table 1 lists the tasks necessary to configure multicast, OSPF, IS-IS, BGP, and RIP.

This guide is presented in an overall logical configuration flow. Each section describes a software area and provides CLI syntax and command usage to configure parameters for a functional area.
