SSR Command Line Interface Reference Manual 495
ospf add network | summary-range
ospf add network | summary-range
Note:
Because the OSPF add network command is misinterpreted with commands
having similar syntax from other vendors, this command will eventually be
dropped from the SSR’s host of CLI commands. The new command is ospf add
summary-range. At this time, however, both are acceptable CLI commands, hence
both are dealt with in this section.
Purpose
Configures summary-ranges on Area Border Routers (ABRs). This allows you to reduce
the amount of routing information propagated between areas.
On the SSR, summary-ranges are created using the ospf add summary-range command –
the networks specified using this command describe the scope of an area. Intra-area Link
State Advertisements (LSAs) that fall within the specified ranges are not advertised into
other areas as inter-area routes. Instead, the specified ranges/networks are advertised as
summary network LSAs. If you specify the restrict option, the summary network LSAs
are not advertised. Each intra-area LSA that does not fall into any range is advertised as
an OSPF Type-3 or 4 LSA.
Format
ospf add network | summary-range <IPaddr/mask> [to-area <area-addr>] [restrict]
[host-net]
Mode
Configure
Parameters
<IPaddr/mask>
IP Address and network mask value representing the summary-range. Example:
16.122.0.0/255.255.0.0 or 16.122.0.0/16.
to-area <area-addr>
OSPF Area with which this summary-range is to be associated.
restrict
If the restrict option is specified for a network/summary-range, then that network is
not advertised in Summary network LSAs.
