When configuring MLAG, Arista recommends that the trunk group command be used on the VLAN used for MLAG peer communication. What is the purpose of the trunk group command?
A.
It groups all the trunks together so that they can traverse the peer-link properly.
B.
It groups the MLAG interfaces together so that they can be reported on both peers.
C.
It prevents the configured VLAN from leaking out onto other trunks.
D.
It ensures that the configured VLAN will be included on all trunks.
The trunk group MLAG-Peer command creates a trunk group, which is a cool way of assigning VLANs to trunks. We now need to assign the same group to the peer-link:
Arista-1(config-vlan-4094)#int po 1
Arista-1(config-if-Po1)#switchport trunk group MLAG-Peer
Now, VLAN 4094 will only be included on trunks that are also assigned to the MLAG- Peer trunk group. By doing this, when we create a new trunk, by default VLAN 4094 will not be included.
In arista worrior
By doing this, when we create a new trunk, by default VLAN 4094 will not be included. This keeps the MLAG peer-link traffic on this link, and only on this link (unless you add the MLAG-Peer trunk group to another trunk, but don’t do that).
Maybe C is correct.
