OSPF Protocol

The Router tab's OSPF Protocol box includes controls that allow you
to specify the following values:
• OSPF Area: This value must be set to the same OSPF area as the
ingress router to which the SA8220 is talking. This can be the
keyword "backbone," an integer, or dotted decimal format
(xxx.xxx.xxx.xxx). The integer range is from 0 to
2,147,483,647, and the default is not active.
• Hello Interval: The number of seconds between hello packets
sent on this interface. This value must match the hello interval of
the ingress router. The valid range is from 1 to 65,535, and the
default is 10.
• Router Dead Interval: The number of seconds the SA8220's
OSPF neighbors should wait before assuming this OSPF SA8220
is down. This value must match the router dead interval of the
ingress router. The valid range is from 1 to 2,147,483,647, and
the default is 40.
Authentication type and key are security mechanisms to
guarantee that routing information is exchanged only with trusted
routers. The type and key together comprise the "authentication
scheme." An OSPF Area can have only one OSPF
Authentication scheme.
• Authentication Type: Allows you to specify the type of OSPF
authentication. To Disable OSPF authentication, click None. To
enable Simple password authentication, click Simple and then
proceed to the Authentication Key field. To enable MD5
authentication, click MD5, then enter an authentication key and
key id.
• Authentication Key: A user-specified string (excluding double
quotes and spaces) used as an authentication password. The
authentication key is from 1 to 8 characters for Simple
authentication, and 1 to 16 characters for MD5 authentication.
• Confirm Authentication Key: Re-enter the Authentication Key to
verify it to the SA8220.
• Key ID: MD5 key id, an integer from 1 to 255. MD5
authentication provides a stronger level of security for OSPF
users.
