highest system ID uses the nickname. The system automatically assigns new nicknames to the other
RBs.
The system resets the TRILL process when the RB's system ID changes.
To configure the system ID and nickname for the RB:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter TRILL view. trill N/A
3. Configure the system
ID for the RB.
system-id system-id
By default, the RB automatically generates a
system ID based on its MAC address upon
startup.
4. Configure the
nickname for the RB.
nickname nickname [ priority
priority ]
By default, TRILL automatically assigns
nicknames to RBs, and the priority for a RB
to hold a nickname is 64.
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. Access ports without the alone attribute can process
only local data frames and Hello frames.
• Hybrid—A hybrid port combines the attributes of an access port and a trunk port, and can process
local data frames and passing data frames.
• Trunk—A trunk port can process passing data frames and some of Layer 2 protocol frames (for
example, LLDP frames), but it cannot process local data frames.
• VR—A VR port is a virtual router port that can forward the following traffic:
{
TRILL data frames.
{
Layer 3 unicast data traffic.
{
Layer 2 and Layer 3 multidestination data traffic.
Configuration restrictions and guidelines
• For the TRILL network to forward Layer 3 traffic, you must configure the link type as VR for TRILL ports
that are connected to an 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. H3C recommends that you reduce the number of announcing VLANs
on VR ports to reduce Hello frames.
