  • Page 5: 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.

    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 7: 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 TRILL uses different mechanisms to forward Layer 2 and Layer 3 traffic.

  • Page 8

    The outer Ethernet header enables traditional Ethernet switches to forward TRILL frames and connect RBs. Multidestination frame forwarding mechanism. • In a TRILL network, RBs perform the following tasks: 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.

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.

    Figure 5 TRILL Layer 3 forwarding A TRILL VR contains multiple member RBs that are configured with the same virtual IP address. All member RBs participate in Layer 3 forwarding. A master RB responds to ARP or ND requests. The master RB is elected by using the following rules: The member RB with the highest priority is elected as the master RB.

    VR ports are used only on P2P links, and both ends of a P2P link must be VR ports. • A VR port trunks all VLANs. HP recommends that you reduce the number of announcing VLANs on • VR ports to reduce Hello frames.

    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.

    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.

    An LSP sent by an RB carries the following TRILL distribution tree information: • The number of TRILL distribution trees that the RB wants all RBs to compute. The maximum number of TRILL distribution trees that the RB can compute (this number is fixed at 15). •...

  • Page 22: Configuring Trill Ecmp Routes

    When a distribution tree is added, the RB switches ingress traffic to the new tree to implement load balancing. However, the RB cannot use the new distribution tree to forward traffic before other RBs are ready to use the new tree. In this case, you can set a delay timer for the RB to switch ingress traffic to the new distribution tree.

    The VR cannot use the IP address of the VLAN interface as a virtual IP address. • The member RBs of a VR must use the same VLAN configurations, virtual IP addresses, and VLAN-interface-to-VPN bindings. The VR cannot use the real IP address of a member RB as a virtual IP address.

  • Page 25: Permitting A Non-trill Device To Learn The Mac Address Of The Trill Vr

    Permitting a non-TRILL device to learn the MAC address of the TRILL VR A non-TRILL device is a device that does not support TRILL or is not enabled with TRILL. When a non-TRILL device is connected to an access RB, the device cannot learn the MAC address of the TRILL VR. User packets destined for the TRILL VR are flooded by the device.
