An administrator is troubleshooting failed cluster peering between three ONTAP clusters for cascaded SnapMirror replication. Cluster1 is peered to Cluster2. Cluster2 is peered to Cluster3.
Cluster1 and Cluster3 do not have an available route to reach each other. Cluster2 can route to both Cluster1 and Cluster3 using dedicated and separate intercluster LIFs.
What ONTAP network component must be configured on Cluster2 to resolve this issue?
