Page 4: 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. -

Page 6: 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 7 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.

Page 14: 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 access ports without the alone attribute and access ports with the alone attribute. Access ports with the alone attribute do not send or receive Hello frames and do not participate in DRB election or AVF negotiation. -

Page 16: Configuring Trill Timers
Step Command Remarks VLAN as the designated VLAN. 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. -
Page 17: Configuring Trill Lsp Parameters And Features
Configuring TRILL LSP parameters and features Setting TRILL LSP parameters You can set the following LSP parameters: • 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 entry that is identified by fewer keys is at a higher level. The incremental flush feature enables the device to compare the outgoing port list and local receiving flag of an entry with its next higher level entry. If the two entries have the same outgoing port list and local receiving flag, the higher level entry is issued to the TRILL FIB. -
