Figure 20-1.7: OSPF Interface Configuration
Parameter descriptions
:
Interface
: Interface identification (e.g., VLAN1).
Priority
: Specify a router priority for the interface. The valid range is 0 – 255; the default value is 1.
Cost
: User specified cost for this interface. It's link state metric for the interface. The field is significant only
when
'IsSpecificCost'
is TRUE. The valid range is 1 - 65535 and the default setting is 'Auto’ cost mode.
FastHelloPackets
: How many Hello packets will be sent per second. The valid range is 1 - 10 and the default
setting is disabled.
Hello Interval
: How many Hello packets will be sent per second. The valid range is 1 - 65535 seconds and the
default value is 10 seconds.
OSPF uses Hello packets and two timers to check if a neighbor is still alive:
Hello
Interval
defines how often the hello packet is sent.
Dead
Interval
defines how long to wait for hello packets before declaring the neighbor dead.
The hello and dead interval values can be different based on the OSPF network type.
Dead Interval
: The time interval (in seconds) between hello packets. The valid range is 1 - 65535 seconds and
the default value is 40 seconds.
Retransmit Interval
: The time interval (in seconds) between Link-State Advertisement (LSA) retransmissions for
adjacencies. The valid range is 3 - 65535 seconds and the default value is 5 seconds.
Auth. Type
: The authentication type:
Simple
Password
: It's using a plain text authentication. A password must be configured, but a simple
password can be read by a packet sniffer.
Message
Digest
: It's message-digest algorithm 5 (MD5) authentication. Keying material must also be
configured. This is the most secure method.
Null
Authentication
: No authentication.
Area
Configuration
: Refer to
Area Authentication
setting on page
317
.
Change Simple Password
