HOWTO: Configure Cross-Vendor VRRP Gateway (Cisco IOS + Arista vEOS)¶
This HOWTO walks through building a shared VRRPv3 default gateway between Cisco CSR1000v and Arista vEOS — two different vendor stacks sharing one virtual IP for a LAN segment. You will configure VRRP master and backup roles, add WAN health tracking to tie priority to real path reachability, and run a structured failover drill with before/after validation.
What this covers:
- VRRPv3 cross-vendor configuration on Cisco IOS-XE and Arista vEOS
- WAN path health tracking tied to VRRP priority decrement
- Structured failover drill with convergence measurement and run records
