To add static routes:
1.
From the sidebar, select
Network Settings - Routes.
Any existing static routes are listed with their Destination
IP/Mask, Gateway, Interface and Metric values shown.
2.
Enter the destination IP, gateway and netmask values in the appropriate fields, then use the drop-down menu
to select the device interface.
3.
Click
Add
.
To delete a static route:
1.
From the sidebar, select
Network Settings- Routes
.
2.
Click on the name of the static route you want to delete, then click
Delete

5.3.5 OSPF and BGP
The appliance supports Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) routing standards and their
associated configurations. An administrator can add, edit and delete OSPF and BGP networks.
OSPF
In order to use OSPF, an administrator must first configure the appliance ID, interfaces and networks settings. By default,
OSPF speaks to all interfaces on the appliance. An administrator cannot add an interface but may change the status of an
existing interface.
An administrator is able to add a network for the appliance to give and receive information from other OSPF nodes within
the network. When adding a network, it must be unique to the appliance. The network value is in CIDR format of an
IP address/netmask, for example: 10.12.1.0/24.
To configure OSPF:
1.
From the sidebar, click
Network Settings - OSPF
.
2.
Check the box to enable OSPF.
NOTE: When OSPF is enabled or disabled, an alert will be sent to the alert manager.
3.
Enter the appliance ID, then click
Apply
. The appliance ID should be an IP address, but it can be any arbitrary
32-bit number. The appliance ID must be unique within the entire OSPF domain.
4. Use the drop-down menus to set the Interfaces to either Active or Passive. OSPF will not speak to any interface
set to Passive.
5.
To add a network, enter the address for the network and its area, then click
Add
.
6. To edit an existing network, check the box next to the network under the Modify an OSPF Network heading.
When finished, click
Apply
.
7.
To delete a network, check the box next to the network, then click
Delete
.
BGP
BGP is one of the key protocols used to achieve internet connection redundancy. BGP appliances use TCP protocol on port
179 to communicate with each other. BGP sends only incremental updates containing the routing entries that have changed
since the last update.
BGP peers are established by manual configuration between appliances to create a TCP session on port 179. Every 30
seconds, a BGP speaker will send keep-alive messages to maintain the connection. Each BGP appliance maintains a
separate TCP session with other BGP appliances to which it is connected.
An Autonomous System (AS) is a group of IT networks run by one or more network operators with a single, clearly defined
routing policy. When exchanging routing information, each AS is identified by a unique number. The 16-bit number range is
from 0 to 65535. From 64512 to 65535 is reserved for private use. Exterior routing protocols such as BGP are used to
exchange routing information between Autonomous Systems. An AS will normally use some interior gateway protocol to
exchange routing information on its internal networks. The network value is in CIDR format of an IP address/netmask, for
example: 10.12.1.0/24. The configured network will be announced to all its neighbors.
