node. Configuration mismatches are logged in the syslog and displayed in the output of the show vlt
inconsistency command.
When you enable VLT unicast, VLAN wildcarding is enabled to support up to 4094 VLANs. If you enable
VLT unicast, the following actions occur:
• L3 routing is enabled on any new IP address / IPV6 address configured for a VLAN interface that is up.
• L3 routing is enabled on any VLAN with an admin state of up.
• For PVLAN, if the IP address is configured for the primary VLAN, L3 routing is enabled.
NOTE: If the CAM is full, do not enable peer-routing.
NOTE: The peer routing and peer-routing-timeout is applicable for both IPv6/ IPv4.

Configuring VLT Unicast

To enable and configure VLT unicast, follow these steps.
1. Enable VLT on a switch, then configure a VLT domain and enter VLT-domain configuration mode.
CONFIGURATION mode
vlt domain domain-id
2. Enable peer-routing.
VLT DOMAIN mode
peer-routing
3. Configure the peer-routing timeout.
VLT DOMAIN mode
peer-routing—timeout value
value: Specify a value (in seconds) from 1 to 65535.
Non-VLT ARP Sync
In the Dell Networking OS version 9.2(0.0), ARP entries (including ND entries) learned on other ports are
synced with the VLT peer to support station move scenarios.
Prior to Dell Networking OS version 9.2.(0.0), only ARP entries learned on VLT ports were synced
between peers.
Additionally, ARP entries resulting from station movements from VLT to non-VLT ports or to different
non-VLT ports are learned on the non-VLT port and synced with the peer node. The peer node is
updated to use the new non-VLT port.
NOTE: ARP entries learned on non-VLT, non-spanned VLANs are not synced with VLT peers.
