7 Managing TRILL
Transparent Interconnect of Lots of Links (TRILL) uses IS-IS to provide transparent Layer 2 forwarding.
TRILL combines the simplicity and flexibility of Layer 2 switching with the stability, scalability, and
rapid convergence capability of Layer 3 routing. All these advantages make TRILL very suitable
for large flat Layer 2 networks in data centers.
Switches implementing TRILL are called "Routing Bridges" (RBs). A TRILL network is a Layer 2
network comprised of RBs, as shown in Figure 16.

TRILL provides the following advantages:
• Ease of configuration.
• Fast convergence upon network topology changes.
• Improved bandwidth and data forwarding efficiency.
TRILL integrates shortest path first (SPF) with the Layer 3 routing technique Equal Cost Multiple
Path (ECMP) for data forwarding.
Managing a TRILL network with VFM
For RBs to work in a TRILL network, you must enable TRILL on the RBs globally as well as on the RB
interfaces.
VFM enables you to configure TRILL parameters on RBs and the RB interfaces individually or in
batches.
Recommended procedure for configuring and managing a TRILL network
Perform the following steps to configure and manage a TRILL network:
1. Import RBs to the TRILL module of VFM.
2. Configure TRILL parameters for RBs individually or in batches.
3. Configure TRILL on newly added RBs, or modify the TRILL parameters of existing RBs.
4. Configure TRILL parameters for RB interfaces.
Managing RBs
With VFM, you can import, query, delete, and synchronize RBs, and configure TRILL parameters
for RBs in batches or individually. You can also enable or disable TRILL on interfaces of an RB,
and configure TRILL parameters on the interfaces.
