OSPF support on L2TP over IPsec
Apart from LAN, WAN1 and WAN2, the user can exchange routes via L2TP over IPsec. OSPF supports a virtual
interface created in L2TP over an IPsec channel. The static routes which are added have to be exchanged over
these interfaces.
L2TP over IPsec wraps a stimulated data link layer in IPsec. Plain IPsec just encrypts the network layer. When the
L2TP over IPsec configuration is saved, the tunnel initiation starts automatically but the establishment of the
tunnel depends on the configuration at the client and the server side, and the response from the server.
Ensure that the L2TP tunnel over the IPsec is established before enabling OSPF.

Toggle ON to enable OSPF.
Displays the physical network interface on which OSPFv2 is Enabled/Disabled.
Enter the area to which the interface belongs. Two routers having a common segment; their
interfaces have to belong to the same area on that segment. The interfaces should belong to the
same subnet and have similar mask.
Helps to determine the OSPFv2 designated router for a network. The router with the highest priority
will be more eligible to become Designated Router. Setting the value to 0 makes the router ineligible
to become Designated Router. The default value is 1. Lower the value means higher the priority.
The number of seconds for Hello Interval timer value. Enter the number in seconds that the Hello
packet will be sent. This value must be the same for all routers attached to a common network. The
default value is 10 seconds.
The number of seconds that a device's hello packets must not have been seen before its neighbors
declare the OSPF router down. This value must be the same for all routers attached to a common
network. The default value is 40 seconds. OSPF requires these intervals to be exactly the same
between two neighbors. If any of these intervals are different, these routers will not become
neighbors on a particular segment.
Enter the cost of sending a packet on an OSPFv2 interface.
Select one of the following authentication types:
• None: The interface does not authenticate OSPF packets.
• Simple: OSPF packets are authenticated using simple text key.
• MD5: The interface authenticates OSPF packets with MD5 authentication.
Enter the authentication key. This field is available when Simple is selected as the Authentication
Type.
If MD5 is selected as the authentication type, enter the MD5 key ID.
If MD5 is selected as the authentication type, enter the MD5 authentication key.
