Description

Add MLAG configuration mapping with coordinated peer updates.

Tasks

  • Map MLAG domain configuration
  • Map peer-link port-channel
  • Map VLAN 4090 (MLAG peer) and 4091 (iBGP)
  • Map peer-address and local-interface
  • Implement coordinated updates (both peers must be configured together)

Challenge: Coordinated Updates

MLAG peers must be configured together to avoid split-brain:

  1. Detect MLAG pair relationship from NetBox
  2. Plan changes for both peers
  3. Apply to both peers in coordinated manner
  4. Validate MLAG state after apply

Key Configuration

mlag configuration
  domain-id leafs
  peer-link port-channel 999
  local-interface vlan 4090
  peer-address 10.0.199.255
