Example of Connecting the ML-Series Cards with Point-to-Point STS/STM Circuits
The three-node RPR-IEEE in Figure 26-6 shows an example of the point-to-point circuits needed.
Figure 26-6 Three Node RPR-IEEE Example
To configure the circuits for the example, you would need to perform these tasks in CTC:
1. Create a circuit from Node 1, East Span to Node 2, West Span.
2. Create a circuit from Node 2, East Span to Node 3, West Span.
3. Create a circuit from Node 3, East Span to Node 1, West Span.
Creating the RPR-IEEE Interface and Bridge Group
The plug-n-play feature of RPR-IEEE automatically discovers topology and advertises station
capabilities. This allows ML-Series cards to become operational without manual intervention when the
ML-Series card is in 802.17 mode and the SONET/SDH circuits are configured. Unlike Cisco
proprietary RPR, RPR-IEEE does not require the user to configure POS interfaces.
The additional Cisco IOS CLI provisioning needed to set up basic, functional RPR is straightforward.
The user needs to complete these tasks:
1. Configure the ML-Series card for integrated routing and bridging (IRB).
2. Create the bridge group.
3. Set the encapsulation on the Ethernet interface.
4. Assign Ethernet interfaces to the bridge group.
5. Enable the Ethernet ports.
