CDRouter-Multiport

Testing more than one way to connect? No problem.

CDRouter Multiport is an add-on module to the base version of CDRouter for testing multiple WAN interfaces and multiple LAN interfaces on CPE routers. The CDRouter Multiport version supports routers with multiple Ethernet interfaces on the WAN, multiple ATM PVC connections from xDSL interfaces, multiple T1/E1 interfaces or any combination of interfaces. CDRouter Multiport also supports multiple LAN interfaces allowing your test setup to verify built-in multi-port Ethernet interfaces along with multiple 802.11 wireless interfaces.

Multiport gives CDRouter the power and flexibility to test multiple interfaces.

Multiport Test Coverage

CDRouter Multiport includes all of the test cases included with the base version of CDRouter. Additionally, it adds several new test modules to verify functionality specific to routers with multiple WAN and LAN ports.

WAN failover

The WAN failover test module verifies failover from one WAN interface to another WAN interface when a failure condition is detected. CDRouter will verify that client traffic from the LAN such as DNS and HTTP correctly fails over to the backup WAN interface. This test module works with routers that have primary and backup WAN interface.

NAT with multiple WAN interfaces

CDRouter Multiport verifies NAT functionality when multiple WAN interfaces are active. CDRouter will verify that each WAN interface is using its correct NAT configuration and verify that NAT continues to work when traffic is arriving across different WAN interfaces.

RIPv1/v2 on the WAN

The multiport RIPv1/v2 extends the coverage of the RIPv1/v2 testing to include RIPv1/v2 over multiple WAN interfaces.

Forwarding

The multiport forwarding test module extends forwarding verification to cover multiple WAN ports and forwarding between multiple LAN ports.

Inter-LAN Traffic and Wireless/Wired Interoperability

CDRouter Multiport can verify multiport LAN side switches and wireless LAN to wired LAN interoperability. When multiple LAN interfaces are used, CDRouter can cycle through all of the base test cases against each LAN interface. In a single test run, CDRouter-Multiport can verify that all LAN side protocols and ALGs work on both wireless and wired interfaces.

Example Test Setup

CDRouter Multiport supports up to 64 unique WAN interfaces and 64 unique LAN interfaces. The diagram below shows an example lab setup using two WAN interfaces.

CDRouter and MultiPort Feature Comparison

CDRouter is available in different versions: the base version of CDRouter and CDRouter MultiPort. The base version of CDRouter uses one WAN interface and one LAN interface. The MultiPort version allows multiple LAN interfaces and multiple WAN interfaces. The chart below compares the testing features of both versions.
