    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.

    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 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 3 Multicast frame forwarding flow RB 4 VLAN 200 TRILL network RB 1...

    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.
  • Page 13 Figure 5 Ping TRILL packet forwarding Tracert TRILL Tracert TRILL enables retrieval of the nicknames of RBs in the path to a destination RB. In the event of network failure, use tracert TRILL to test network connectivity and identify failed nodes. Tracert TRILL operates as shown in Figure RB 1 sends RB 3 an OAM echo request with a hop count value of 0.

    An edge port is used to connect the spanning tree network to the TRILL network. The edge port can transit to the forwarding state before DRB election is finished. This prevents multiple DRBs from being elected. For more information about spanning tree protocols, see Layer 2—LAN Switching Configuration Guide.

Using ping TRILL and tracert TRILL to test network connectivity 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.

  • Page 20: Configuring Trill Timers

    Configuring TRILL timers You can configure the following TRILL timers: • Hello interval and Hello multiplier—The 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. The adjacency holding time is obtained by multiplying the Hello interval by the Hello multiplier.
  • Page 21 • LSP maximum age—The RB uses the LSP maximum age as the remaining lifetime of the LSPs that it originates. When the RB detects that the remaining lifetime of an LSP reaches 0 seconds in the LSDB, the RB performs the following tasks: Removes the LSP's content.
