ASN: The AS (Autonomous System)
number is one of the essential elements
of BGP.
Router-ID: This sets the router-ID of the
BGP 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 BGP domain to the BGP speaker:
bad things will happen if multiple BGP
speakers are configured with the same
router-ID.
Enabled: Click to enable/disable the
policy. (Default: enabled.)
Networks Associated with ASN or IPv6
Networks Associated with ASN: To configure
a BGP router, you need an AS number. An AS
number is an identification of autonomous
system. BGP protocol uses the AS number
for detecting whether the BGP connection
is internal one or external one. Use the IPv4
address and netmask or IPv6 address with a CIDR notation prefix length to define the address range.
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.
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.
