I have two pairs of 3210s. The default gateway of the systems are via the management interface IP range, so that they are reachable remotely on the e0M interfaces.
However, this is causing snapmirror replication to use those interfaces as well, which is undesirable from a speed/data path persepctive.
I have considered putting e0M into its own ipspace, but then how would I manipulate its routing table as it would not be in a vfiler.
Any other ideas about having e0M reachable from anywhere, but still use a different vif as the default gateway for generic traffic on the system?
There's nothing special about snapmirror, it just uses the standard routing table like it would on a regular unix host. If you want to send your snapmirror traffic over a specific interface, then make sure that the target filer is reachable via that interface, for example by making sure that the target is in the same VLAN as the source.
What we do is send all production (NFS) traffic over private IP space in vlan's that aren't routed (no default gateway). Our vif interfaces are divided into multiple different vlan interfaces. If necessary, you can send the snapmirror traffic over such a vlan interface by making sure that the destination is in the right vlan.
