Link Aggregation 1097
Basic Configuration Example
This example shows the configuration of the two MLAG peers and a single
MLAG partner in the simplest possible configuration. No MLAG peer
priorities are configured, nor is UDLD enabled on the peer-link. DCPDP is
not enabled. The default spanning tree configuration is used and spanning-
tree is disabled on the peer link. A system MAC address is assigned to both
MLAG peers. The system virtual MAC address is used in the spanning-tree
BPDUs and LACPDUs.
