create ospf virtual_link
Purpose Used to create an OSPF virtual interface.
Syntax create ospf virtual_link <area_id> <neighbor_id> {hello_interval <sec 1-65535> |
dead_interval <sec 1-65535> | authentication [none | simple <password 8> | md5 <key_id
1-255>]}
Description This command is used to create an OSPF virtual interface.
Parameters <area_id> – A 32-bit number in the form of an IP address (xxx.xxx.xxx.xxx) that uniquely identifies the OSPF
area in the OSPF domain.
<neighbor_id> – The OSPF router ID for the remote area.This is a 32-bit number in the form of an IP address
(xxx.xxx.xxx.xxx) that uniquely identifies the OSPF area in the OSPF domain.This is the router ID of the
neighbor router.
hello_interval <sec 1-65535> – Allows the specification of the interval between the transmission of OSPF Hello
packets, in seconds. Between 1 and 65535 seconds can be specified.The Hello Interval, Dead Interval,
Authorization Type, and Authorization Key should be the same for all routers on the same network.
dead_interval <sec 1-65535> – Allows the specification of the interval between the receipt of Hello packets
from a neighbor router before the selected area declares that router down.An interval between 1 and 65535
seconds can be specified.The Dead Interval must be evenly divisible by the Hello Interval.
authentication – Enter the type of authentication preferred.The user may choose between:
none – Choosing this parameter will require no authentication.
simple <password 8> – Choosing this parameter will set a simple authentication which includes
a case-sensitive password of no more than 8 characters.
md5 <key_id 1-255> – Choosing this parameter will set authentication based on md5 encryption.A previously
configured MD5 key ID (1 to 255) is required.
Restrictions Only administrator-level users can issue this command.
