Overview
Consider a sample topology in which a router, Router A, functions as a reflector of the
test frames for an RFC 2544-based benchmarking test. The logical customer edge
(CE)-facing interface and inet family are configured on Router A. Router A is not part of
a pseudowire and therefore, a Layer 3 family configuration is required on it. Router A,
which is a customer edge device, CE1, is connected to Router B, which functions as a
provider edge device, PE1, over an Ethernet pseudowire in the UNI direction with EtherType
or Layer 2 Ethernet payload. The logical interface, CCC family, and UNI direction are
configured on Router B. Router B or PE1 is connected over an Ethernet pseudowire in the
NNI direction to a provider edge device at the remote site, PE2. The link between CE1 and
PE1 is an Ethernet Layer 2 network and it can be configured with any EtherType value.
The link between PE1 and PE2 is an Ethernet line (E-LINE) or an Ethernet Private Line
(EPL) that has Layer 2 payload and Layer 3 transport sent over it. Router B or PE1 functions
as an initiator and terminator of the test frames that are sent to Router A and reflected
back from it.
This benchmarking test is used to compute the performance attributes in the
user-to-network interface (UNI) direction of an Ethernet pseudowire service between
Router A and Router B. Data traffic arriving from a network-to-network interface (NNI)
toward the customer edge is ignored while the test is in progress. Packets from the CE
are not sent toward the NNI because all packets are assumed to be test probes.
Figure 73 on page 1376 shows the sample topology to perform an RFC 2544 test for the
UNI direction of an Ethernet pseudowire service.
