Chapter 5: OSPF Configuration Guide
SSR User Reference Manual 5 - 5
To configure OSPF area parameters, enter the following commands in the Configure
mode.
Create Virtual Links
In OSPF, virtual links can be established:
• To connect an area via a transit area to the backbone
• To create a redundant backbone connection via another area
Each Area Border Router must be configured with the same virtual link. Note that
virtual links cannot be configured through a stub area.
To configure virtual links, enter the following commands in the Configure mode.
Specify an OSPF stub area.
ospf set area <area-num> stub
Specify the cost to be used to inject a
default route into an area.
ospf set area <area-num> stub-cost <num>
Specify the authentication method to be
used by neighboring OSPF routers.
ospf set area <area-num> [stub]
[authentication-method none|simple|md5]
Create a virtual link.
ospf add virtual-link
<number-or-string>
[neighbor <IPaddr>] [transit-area <area-
num>]
Set virtual link parameters.
ospf set virtual-link <number-or-string>
[state disable|enable] [cost <num>]
[retransmit-interval <num>] [transit-delay
<num>] [priority <num>] [hello-interval
<num>] [router-dead-interval <num>] [poll-
interval <num>]
