Out-of-Path with VRRP Peering to a WAN Router : Creating Tunnels
Creating Tunnels
Create a tunnel between Appliances A1 and B. This involves accessing each appliance, in turn, and creating a tunnel to the other (remote) appliance.
After the tunnels are up, we’ll verify that the subnet table has updated.
w
To create a tunnel from A1 to B
1
From a browser, access Appliance A1.
2
From the menu bar, select Configuration > Tunnels. The Tunnels page appears.
3
Click Add Tunnel.
a
In the Name field, assign a locally significant name for the tunnel.
b
In the Admin field, accept the default value, Up.
c
Leave Auto MTU selected. This allows the tunnel MTU to be discovered and negotiated automatically. When selected, this overrides the MTU setting.
d
In the Local IP field, the Appliance Manager prefills the IP address for the local appliance.
e
In the Remote IP address field, enter the data path IP address of the remote Silver Peak appliance.
f
Leave Auto Max BW selected, so the appliance uses the lower of the two system bandwidths.
If you wanted to configure this manually, then you would deselect Auto Max BW and, in the Max BW field, enter the maximum bandwidth for this tunnel. The value must be less than or equal to the upstream bandwidth of your WAN connection.
g
Leave the Min BW at its default, 32 [Kbps].
h
Click Apply.
i
Save the changes.
The tunnel status doesn’t change to Up until a tunnel is configured at both ends. So, we’ll now configure a tunnel from B to A1.
w
To create a tunnel from B to A1
1
From a browser, access Appliance B.
2
From the menu bar, select Configuration > Tunnels. The Tunnels page appears.
3
Click Add Tunnel.
a
In the Name field, assign a locally significant name for the tunnel.
b
In the Admin field, accept the default value, Up.
c
Leave Auto MTU selected. This allows the tunnel MTU to be discovered and negotiated automatically. When selected, this overrides the MTU setting.
d
In the Local IP field, the Appliance Manager prefills the IP address for the local appliance.
e
In the Remote IP address field, enter the data path IP address of the remote Silver Peak appliance.
f
Leave Auto Max BW selected, so the appliance uses the lower of the two system bandwidths.
g
Leave the Min BW at its default, 32 [Kbps].
h
Click Apply.
i
Save the changes.
Within a few seconds, the tunnel Status changes to Up - active. Click Refresh, if required.
Now that the tunnels are up, the appliances can begin advertising subnet information to each other.
w
To verify that the Subnet table is current
On Appliance B, examine the subnet table by going to Configuration > Subnets.
Now that Appliance B has learned the remote appliance’s subnet(s), it automatically places packets with destinations in learned subnets into the correct tunnels.
