  • Page 8: Configuring Trill

    Configuring TRILL TRansparent Interconnection 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 9 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: 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 by using different forwarding mechanisms.
  • Page 11 Compute a TRILL distribution tree for each VLAN based on the LSDB. • • Guide the forwarding of multidestination frames in each VLAN by using its TRILL distribution tree. 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 12: Protocols And Standards

    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. This improves the load sharing performance.

    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 avoids loops. For more • information about loopback detection, see Layer 2—LAN Switching Configuration Guide. If IRF is used, retain the IRF bridge MAC address permanently. Otherwise, traffic interruption might •...

  • Page 14: Enabling Trill

    Enabling TRILL After you enable TRILL on a port, TRILL can operate correctly by using default settings. A port with TRILL enabled is called a TRILL port.

Enabling TRILL pseudonode bypass This feature disables a DRB from generating LSPs for the pseudonode when the DRB has only one neighbor on a broadcast network.

  • Page 22: Configuring Trill Distribution Trees

    Configuring TRILL distribution trees Setting basic distribution tree parameters In a TRILL network, RBs perform the following tasks: Compute TRILL distribution trees according to the LSDB. • Use the TRILL distribution trees to guide the forwarding of multidestination frames. • An RB with a higher priority is selected as the root bridge of a TRILL distribution tree.

  • Page 23: Enabling Load Balancing Over Trill Distribution Trees

    Enabling load balancing over TRILL distribution trees By default, ingress traffic is not load balanced over TRILL distribution trees after a forwarding VLAN is deleted on the RB. To load balance ingress traffic of the remaining forwarding VLANs over the existing distribution trees, you can enable load balancing over TRILL distribution trees.
