  • Page 4: Configuring Trill

    Configuring TRILL Transparent Interconnect 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.

    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 6: 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 7: Protocols And Standards

    Multi-destination frame forwarding mechanism In a TRILL network, RBs compute a distribution tree for each VLAN according to the LSDB and use the 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...

  • Page 8: Trill Configuration Task List

    TRILL configuration task list When you configure TRILL, follow these guidelines: Configuration in Ethernet interface view takes effect on only the current port. Configuration in • aggregate interface view takes effect on the current interface and its member ports. Configuration on the member port of an aggregate interface takes effect after the member port leaves the aggregation group.

  • Page 9

    When you set up a TRILL network, avoid the case that multiple TRILL neighbors are established for • one RB port, as shown in Figure 4 Figure Figure 4 shows a typical network where two TRILL neighbors are established for the same port of an RB.

  • Page 10: Configuring The Link Type Of A Trill Port

    Configuring the link type of a TRILL port The following link types are available for a TRILL port: Access—Access ports include the following types: • Access port without the alone attribute—Processes only local data frames and Hello frames. Access port with the alone attribute—Does not send or receive Hello frames and does not participate in the DRB election or AVF negotiation.

  • Page 11: Configuring Trill Timers

    Designated VLAN—VLAN that forwards TRILL frames except Hello frames between RBs. On the HP • 6125XLG Blade switch of Release 2306, the designated VLAN of a link is the lowest-numbered enabled VLAN of the link. Forwarding VLAN—VLANs for which an RBridge port is appointed VLAN forwarder on the port.

    Step Command Remarks Enter system view. system-view Enter Ethernet or interface interface-type aggregate interface interface-number view. The default setting is 10 seconds. This command sets the Hello interval for the Configure the Hello trill timer hello interval RB. The Hello interval of the DRB is 1/3 of the interval.

  • Page 13: Configuring Distribution Trees

    Step Command Remarks Enter Ethernet or interface interface-type aggregate interface interface-number view. Configure the minimum LSP interval and the By default, the minimum LSP interval is 10 trill timer lsp interval [ count maximum number of milliseconds, and the maximum number of count ] LSPs transmitted per LSPs transmitted per time is 5.

  • Page 14: Enabling Logging Of Trill Neighbor Changes

    When N equal-cost links exist in the network, each TRILL distribution tree selects an equal-cost link for forwarding packets through J mod N in root bridge priority order. J is the priority sequence number of a multicast tree and starts from 0. As shown in Figure The link directly connecting RB 1 to RB 3 is assigned to the TRILL distribution tree rooted at RB 3.

    GR Helper—A neighbor of the GR Restarter. It helps the GR Restarter to complete the GR process. • To configure TRILL GR: Step Command Remarks Enter system view. system-view Enter TRILL view. trill Enable GR for TRILL. graceful-restart By default, GR is disabled for TRILL. (Optional.) Configure graceful-restart interval The default setting is 300 seconds.
