Page 8: Configuring Trill
Configuring TRILL TRansparent Interconnection of Lots of Links (TRILL) uses IS-IS to provide transparent Layer 2 forwarding. Overview 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. -
Page 9: How Trill Works
Figure 1 TRILL data frame format Table 1 describes the fields in the TRILL header. Table 1 TRILL header fields Field Description Ethertype The Ethertype is fixed to TRILL. Version number, which is 0. When an RB receives a TRILL frame, it checks the V field and drops the frame if the V field is not 0. -
Page 10: Trill Forwarding Mechanisms
TRILL forwarding mechanisms Different types of frames are forwarded by using different forwarding mechanisms. The following sections describe these mechanisms. Unicast frame forwarding mechanism As shown in Figure 2, a unicast frame is forwarded as follows: When a unicast frame enters the TRILL network, the ingress RB encapsulates the original Ethernet frame with the following headers: A TRILL header (similar to an IP header). - Page 11 bridge, it is distributed throughout the TRILL distribution tree. Then, the TRILL frame is de-encapsulated by RB 3 and sent to the destination station S2. Because the network segment where RB 4 resides does not have a receiver of this frame, RB 4 drops the frame.

Figure 4 Multicast ECMP RB 1 Cost = 2 RB 2 RB 3 RB 4 TRILL distribution trees support Equal Cost Multiple Path (ECMP), also known as multicast ECMP. When multicast ECMP is enabled, TRILL assigns equal-cost links to multiple TRILL distributions trees. -

Feature compatibility requirements When you use TRILL with other features, follow these restrictions and guidelines: • Do not enable both TRILL and EVB on a port. The allowed VLAN list of a TRILL-enabled port cannot overlap with that of an EVB-enabled port. -

Page 18: Configuring Trill Lsp Parameters And Features
• AVF inhibition time—As the AVF of a VLAN, the RB guarantees that frames of the VLAN enter and leave a broadcast network through the same port. Other RBs on the broadcast network do not process frames from the VLAN. To avoid loops, the RB suppresses its AVF role during the inhibition time when one of the following conditions exists: The RB detects a root bridge change on the broadcast network. - Page 19 • LSP generation timer parameters—By adjusting the TRILL LSP generation timer parameters, you can prevent frequent network changes from consuming excessive bandwidth and device resources. When the network is stable, the LSP generation timer is set to the minimum interval for each LSP generation.
