IP Routing Commands
4-277
4
•
authentication
- Specifies the authentication mode. If no optional
parameters follow this keyword, then plain text authentication is used along
with the password specified by the
authentication-key
. If
message-digest
authentication is specified, then the
message-digest-key
and
md5
parameters must also be specified. If the
null
option is specified, then no
authentication is performed on any OSPF routing protocol messages.
•
message-digest
- Specifies message-digest (MD5) authentication.
•
null
- Indicates that no authentication is used.
•
hello-interval
seconds
- Specifies the transmit delay between sending
hello packets. Setting the hello interval to a smaller value can reduce the
delay in detecting topological changes, but will increase the routing traffic.
This value must be the same for all routers attached to an autonomous
system. (Range: 1-65535 seconds; Default: 10 seconds)
•
retransmit-interval
seconds
- Specifies the interval at which the ABR
retransmits link-state advertisements (LSA) over the virtual link. The
retransmit interval should be set to a conservative value that provides an
adequate flow of routing information, but does not produce unnecessary
protocol traffic. However, note that this value should be larger for virtual
links. (Range: 1-3600 seconds; Default: 5 seconds)
•
transmit-delay
seconds
- Estimates the time required to send a link-state
update packet over the virtual link, considering the transmission and
propagation delays. LSAs have their age incremented by this amount
before transmission. This value must be the same for all routers attached
to an autonomous system. (Range: 1-3600 seconds; Default: 1 seconds)
•
dead-interval
seconds
- Specifies the time that neighbor routers will wait
for a hello packet before they declare the router down. This value must be
the same for all routers attached to an autonomous system.
(Range: 1-65535 seconds; Default: 4 x hello interval, or 40 seconds)
•
authentication-key
key
- Sets a plain text password (up to 8 characters)
that is used by neighboring routers on a virtual link to generate or verify the
authentication field in protocol message headers. A separate password can
be assigned to each network interface. However, this key must be the same
for all neighboring routers on the same network (i.e., autonomous system).
This key is only used when authentication is enabled for the backbone.
•
message-digest-key
key-id
md5
key
- Sets the key identifier and
password to be used to authenticate protocol messages passed between
neighboring routers and this router when using message digest (MD5)
authentication. The
key-id
is an integer from 1-255, and the
key
is an
alphanumeric string up to 16 characters long. If MD5 authentication is used
on a virtual link, then it must be enabled on all routers within an autonomous
system; and the key identifier and key must also be the same for all routers.
