OSPF
OSPF (Open Shortest Path First) version 2 is a routing protocol described in RFC2328, OSPF Version 2. OSPF
is an IGP (Interior Gateway Protocol). Compared with RIP, OSPF can provide more scalable network support
and faster convergence times. OSPF is widely used in large networks such as ISP (Internet Service Provider)
backbone and enterprise networks.
OSPF Areas
•
Area
: Areas are identified by an ID.
•
Default Cost
: Set the cost of default-summary LSAs announced to stubby areas.
•
Stub Area
: Configure area to be stub area.
•
No-Summary
: Prevents ABR from injecting inter-area summaries into the specified stub area
OSPF Editor
•
Router ID
: This sets the router-ID of the OSPF
process. The router-ID may be an IP address
of the router, but need not be – it can be any
arbitrary 32-bit number. However it
MUST
be
unique within the entire OSPF domain to the
OSPF speaker.
•
Authentication Key
: Set OSPF authentication
key to a simple password. After setting
authentication key, all OSPF packets are
authenticated. The authentication key has a
maximum length of eight characters.
•
Enabled
: Click to enable/disable the policy.
(Default: enabled.)
Network Areas
: Areas are identified by an ID
number. Use the IP address and netmask fields to
associate a network with this policy.
Redistribute Routes
: Redistribute routes of
the specified protocol or kind into BGP, with
the metric type and metric set (if specified),
filtering the routes using the given route map
(if specified). Redistributed routes may also be
filtered with distribute lists.
•
Type
: The type is the source of the route.
Select from: Main, Connected, Static, RIP, OSPF.
Neighbor Options
or
IPv6 Neighbor Options
: Creates a new neighbor identified by remote ASN and IP address.
Redistribute Routes
: Redistribute routes of the specified protocol or kind into BGP, with the metric type and
metric set if specified, filtering the routes using the given route map if specified. Redistributed routes may
also be filtered with distribute lists.
•
Type
: The type is the source of the route. Select from: Main, Connected, Static, RIP, and OSPF.
•
Metric
: Numerical priority of the route.
•
Route Map
: Route maps provide a means to filter and/or apply actions to routes, allowing policies to be
applied to routes.
