  • Page 3: Introduction

    CRR-1000 routers can be configured with varying numbers of Ethernet interfaces. The Terms CRR-1000 and CRR are interchangeable and are used to refer the same CRR-1000 family of routers. This quick-start guide assumes a CRR-1000 with two native CPU interfaces (eth0 and eth1) and a separate, multi-port switch core.

  • Page 4: Ssh Paramaters

    3 Common CLI Commands The following is a list of commonly used commands on the CRR-1000. 3.1 Interface Information (show ip) To view a router’s physical interface information such as hardware address, IP addresses, and link state, enter “show ip”...

  • Page 5: Icmp Echo (Ping)

    3.2 ICMP Echo (ping) An ICMP echo (ping) message can be generated from the CRR-1000 router with the “ping” command, e.g.: admin@CRR> ping 192.168.100.1 PING 192.168.100.1 (192.168.100.1) 56(84) bytes of data.

    CRR-1000. In its default, “out of the box” configuration, the CRR-1000’s firewall allows all output and forward traffic. By default, the CRR-1000 blocks most input traffic with the notable exceptions of SSH and ping.

  • Page 7: Viewing The Firewall Policy (Show Filter Policy)

    CRR-1000 Quick Start Guide Important Note: The default firewall policy is configured to make it easy for users to access the router over SSH, test its features, and experiment with configuration when used for the first time. For deployment scenarios, we highly recommend changing the filter policies to DENY for all chains and allowing network traffic to/from known destination/sources only if possible for maximum security.

    CRR-1000 Quick Start Guide 5.1 FRR Configuration FRR service uses the open source Free Range Routing project which supports Cisco’s IOS-like CLI to configure the router.

  • Page 13: Static Routing: Two Routers, Three Subnets

    CRR-1000 Quick Start Guide 5.2.2 Static Routing: Two Routers, Three Subnets The CRR-1000s in this example use static routes and require the hardware addresses of the physical interfaces, as in the previous example. The configuration necessary for CRR is similar to the previous exercise, except static routes will be set up on each router to route traffic.

    5.2.3 Dynamic Routing: Two Routers, Four Subnets The picture below shows two CRR-1000 routers and two networks between them. In the previous examples, the link type was configured as Simple for all links, but in this exercise the links between the two CRRs are of type Core.

    CRR-1000 Quick Start Guide "HardwareAddress" : "xx:xx:xx:xx:xx:xx" 5.2.4 Bootstrap Router Example The Bootstrap Router is an important concept to understand when using ARES. ARES performs neighbor discovery of other CRR-1000s via multicast. When the network link between two CRR-1000s does not support multicast, such as certain IP radios, a Bootstrap Router is required.
