Usage Guideline
The
area range
command is used only with Area Border Routers. It is used to
consolidate or summarize routes for an area. The result is that a single summary
route is advertised to other areas by the ABR. Routing information is condensed
at area boundaries. External to the area, a single route is advertised for each
address range.
Examples
The following example specifies one summary route to be advertised by the Area
Border Routers to other areas for IPv6 prefix 2001:0DB8:0:1::/64 and for the
Router ID 20.0.1.10.
Syntax Description
AREA-ID
Identifier of the area for which routes are to be summarized. It can be specified
as either a decimal value or as an IPv4 prefix.
IPv6-PREFIX
IPv6 prefix
PREFIX-LENGTH
IPv6 prefix length
advertise
(Optional) Advertise and generate a Type 3 Inter-Area Prefix link-state
advertisement (LSA) for the specified address range.
not- advertise
(Optional) Sets the status to
DoNotAdvertis
e for the specified address range.
The Type 3 Inter-Area Prefix LSA is suppressed, and the component networks
remain hidden from other networks.
