NOTE: If VRRP is configured in a Virtual Link Trunking (VLT) environment both switches act as active forwarders by default. Ensure that matching routing entries exist on each peer so that L3 reachability is the same.
Page369 VRRP configuration VRRP specifies a master, or active, router that owns the next-hop IP and MAC address for end stations on a LAN. The master router is chosen from the virtual routers by an election process and forwards packets sent to the next-hop IP address.
Page133 Static Anycast Gateway (SAG) allows multiple switches to simultaneously route packets using a common gateway address in an active/active router configuration. Each switch is configured with the same set of virtual IP address and a virtual MAC address.

その際にVRRPとMC-LAGを併用しGWの冗長化とレイヤー2の負荷分散を行いたいと考えています。
併用可能なのかと併用する場合の注意点等あればご教示お願い出来ないでしょうか。
→OS10であれば併用可能です。その場合VRRPとMC-LAGの併用時にデフォルトでVRRP active-active forward (Active/Active構成できる)となるので負荷分散、冗長性を保つことができます。

しかしSONiC Distributionの場合、併用は可能ですがVRRP active-active forward相当の機能が設定できないため、冗長性は保てますが、負荷分散効果を期待することはできないと思います。(Master/Backupのみの設定になるのでActive -Standby構成のみ)
GatewayでのActive /Active構成をしたい場合はstatic anycast gateway (SAG)を使うことで実現ができるのではないでしょうか。(MCLAGとの併用もできますし)
