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.
• On a VLAN interface, TRILL VRs operate only when the interface is up.
Configuration procedure
To create a TRILL VR:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN interface view. interface vlan-interface
vlan-interface-number
N/A
3. Create a TRILL VR and
assign a virtual IP address
to the VR.
• Create an IPv4 VR:
trill vr vrid vr-id virtual-ip virtual-address
• Create an IPv6 VR:
trill vr ipv6 vrid vr-id virtual-ip
virtual-address [ link-local ]
By default, no TRILL VRs exist.
Associating a TRILL VR with a track entry
A TRILL VR can collaborate with network quality analyzer (NQA) or bidirectional forwarding detection
(BFD) through a track entry to monitor the uplinks of the member RBs. NQA or BFD sends the uplink status
changes to the Track module. Based on the detection results, the Track module changes the state of the
track entry and informs the TRILL module of the change. Then the TRILL module can react to the change
to avoid traffic interruption and network performance degradation.
For information about NQA, see Network Management and Monitoring Configuration Guide.
For more information about BFD and Track, see High Availability Configuration Guide.
To associate a TRILL VR with a track entry:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN interface view. interface vlan-interface
vlan-interface-number
N/A
3. Associate a TRILL VR with a
track entry.
trill vr [ ipv6 ] vrid vr-id track
track-entry-number
By default, a TRILL VR is not associated
with any track entry.
You can associate a track entry only to
an existing TRILL VR. A TRILL VR can be
associated with a maximum of eight
track entries.
