Usage
Information
To configure the VLAN from where the VLT peer forwards packets received over
the VLTi from an adjacent VLT peer that is down, use the peer-down-vlan
parameter. When a VLT peer with bare metal provisioning (BMP) is booting up, it
sends untagged DHCP discover packets to its peer over the VLTi. To ensure that
the DHCP discover packets are forwarded to the VLAN that has the DHCP server,
use this configuration.
primary-priority
Assign the priority for master election among VLT peers.
