To add, edit, or delete a subnet, you must select an individual subnet from the navigation panel and click in Edit. That opens a new browser tab on the specific appliance’s Subnets page.
Subnet sharing is one of the three strategies that Silver Peak uses to auto-optimize all IP traffic, automatically directing flows to the appropriate tunnel. Auto-optimization strategies reduce the need to create explict route map entries to optimize traffic. The other two strategies are TCP-based auto-opt and IP-based auto-opt.Note Enabled by default, the global settings for all three reside on the Templates tab, under System.
•
n Subnet/Mask: Actual subnet to be shared or learned
n Metric: Metric of the subnet. Value must be between 0 and 100. When a peer has more than one tunnel with a matching subnet (for example, in a high availability deployment), it chooses the tunnel with the greater numerical value.
n Is Local: Specifies if the subnet is local to this site.The appliance sets this parameter for automatically for locally connected subnets of the appliance.
• Select this option for a manually added subnet if all the IP addresses in the subnet are known to be local.
• Deselect this option if the subnet is so large (for example, 0.0.0.0/0) that it may include IP addresses that are not local to this appliance. If a subnet is too wide, and it’s marked local, then the stats will count any pass-through packets with an IP address within that range as WAN-to-LAN.
n Advertise to Peers: Selected by default, it shares the subnet information with peers. Peers then learn it. To add a subnet to the table without divulging it to peers, yet, deselect this option.
n Exclude: Use this option to prevent optimization of more specific subnets from a wider advertised subnet range.
n Type of subnet:
• Auto (added by system) = automatically added subnets of interfaces on this appliance
• Added by user = manually added/configured subnets for this appliance
• Learned from peer = subnets added as a result of exchanging information with peer appliances
n SaaS Application Name: If the subnet is associated with a SaaS service, the name displays here.
n Learned from Peer: Which peer appliance advertised (and shared) this subnet information
