Patton electronic SmartNode 4110 Series manual Examples, Basic static IP routing example

SmartWare Software Configuration Guide 22 • Basic IP routing configuration

In this routing table two default routes (0.0.0.0/0) are defined. The first default route is valid for packets of the class local-voice only. The second default route is valid for all packets. Thus voice packets generated locally (traffic-class local-voice) will travel via the gateway (Nexthop) 172.16.32.1. All other packets will travel via the gateway (Nexthop) 172.16.32.2.

NOTE: If the second default route was missing, there would be no default route for packets of traffic-class other than local-voice.

The following modified commands are used with policy routing:

Route—refer to the ‘route’ command in the subsection “Configuring static IP routes” on page 237 in this chapter.

Ping—refer to the ‘ping’ command described in the subsection “Testing connections with the ping command” on page 127 in Chapter 10: IP interface configuration.

Traceroute—refer to the ‘traceroute’ command described in the subsection “Traceroute” on page 130 in Chap- ter 10: IP interface configuration.

Basic static IP routing example

Figure 37 shows an Internetwork consisting of three routers, a SmartNode device in the middle, and the four autonomous networks, with network addresses 10.1.5.0/16, 172.16.40.0/24, 172.17.100.0/24, and 10.2.5.0/

16. The SmartNode shall be configured for the following IP routing scenario:

All packets for the Workstation with IP address 10.1.5.10 shall be forwarded to the next-hop router Calvin. All packets for network 10.2.5.0/16 shall be forwarded to the next-hop router Hobbes.
