Page 9: Configuring Trill
Configuring TRILL Transparent Interconnect of Lots of Links (TRILL) uses IS-IS to provide transparent Layer 2 forwarding. TRILL requires a license. For information about feature licensing, see Fundamentals Configuration Guide. Overview TRILL combines the simplicity and flexibility of Layer 2 switching with the stability, scalability, and rapid convergence capability of Layer 3 routing. - Page 10 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 11: How Trill Works
How TRILL works TRILL establishes and maintains adjacencies between RBs by periodically advertising Hello frames, distributes LSPs among RB neighbors, and generates an LSDB for all RBs in the network. Based on the LSDB, each RB uses the SPF algorithm to calculate forwarding entries destined to other RBs. TRILL forwarding mechanisms Different types of frames are forwarded using different forwarding mechanisms. - Page 12 Compute a TRILL distribution tree for each VLAN according to the LSDB. • • Use the TRILL distribution tree to guide the forwarding of multi-destination frames, which include multicast, broadcast, and unknown unicast frames in the VLAN. As shown in Figure 3, when a multicast frame from VLAN 10 enters the TRILL network, RB 1, which is an ingress RB, encapsulates the multicast frame into a TRILL frame.

Page 13: Protocols And Standards
Figure 4 Multicast ECMP RB 3 RB 2 RB 4 RB 1 Cost = 1 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 different TRILL distributions trees. This improves the load sharing performance. -
Page 14: Trill Configuration Task List
For more information about spanning tree protocols, see Layer 2—LAN Switching Configuration Guide. H3C recommends not enabling loop detection on TRILL ports, because TRILL networks prevent loops • from being generated. For more information about loopback detection, see Layer 2—LAN Switching Configuration Guide. -

Page 19: Configuring Trill Timers
Configuring TRILL timers You can configure the following TRILL timers: • Hello interval and Hello multiplier—An RB advertises Hello frames at the Hello interval to maintain a TRILL adjacency. The shorter the Hello interval, the faster the network convergence. However, a shorter Hello interval consumes more system resources. - Page 20 keeps the LSP's digest, and purges the LSP from the network by advertising the LSP that has the remaining lifetime set to 0. LSP refresh interval—When the remaining lifetime of a locally originated LSP is no greater than • (maximum age – refresh interval), the LSP is refreshed even if no change occurs to it. This mechanism avoids frequent LSP aging and ensures network stability.
