Layer 3 Routing Commands 1700
retransmit-interval and transmit-delay. If the area has not been previously
created, it is created by this command. If the area already exists, the virtual-
link information is added or modified.

• area-id—Identifies the OSPF stub area to configure. (Range: IP address or
decimal from 0-4294967295)
• router-id—Valid IP address.
• authentication—Specifies authentication type.
• message-digest —Specifies that message-digest authentication is used.
• null—No authentication is used. Overrides password or message-digest
authentication if configured for the area.
• hello-interval seconds—Number of seconds to wait before sending hello
packets to the OSPF virtual interface. (Range: 1–65535)
• dead-interval seconds—Number of seconds to wait before the OSPF
virtual interface on the virtual interface is assumed to be dead. (Range: 1–
65535)
• retransmit-interval seconds—The number of seconds to wait between
retransmitting LSAs if no acknowledgment is received. (Range: 0–3600)
• transmit-delay seconds—Number of seconds to increment the age of the
LSA before sending, based on the estimated time it takes to transmit from
the interface. (Range: 0–3600)
• md5—Use MD5 Encryption for an OSPF Virtual Link.
• key—Authentication key for the specified interface. (Range: 8 bytes or less
if the authentication type is simple and 16 bytes or less if the type is
encrypt.)
