44 OSPF: Summary Routes for Routes Distributed in OSPF Release Note
Software Version 2.7.4
C613-10444-00 REV A
OSPF: Summary Routes for Routes
Distributed in OSPF
This enhancement enables you to specify one or more summary address
ranges. Each summary range specifies a network/mask pair. This becomes the
network and mask for the external LSA that OSPF creates when any routes
within the network range are distributed into OSPF. Therefore OSPF only
advertises the network and mask of the summary, not the network and mask of
the individual routes that initiate the advertisement.
Each summary range also optionally specifies whether matching routes are
advertised or not, and what the route tag of the AS external LSA is.
New Commands
add ospf summaryaddress
Syntax ADD OSPF SUMMaryaddress=ipadd MASK=ipadd
[ADVertise={ON|OFF|YES|NO|True|False}] [TAG=0..65535]
The tag parameter specifies the tag value that OSPF places in the OSPF AS
external LSAs created as a result of redistributing routes. The default tag value
is 0. This tag setting overrides tags set by the original route and by the route
map used to select the sub-routes for redistribution, so by default the summary
route has a tag of 0.
delete ospf summaryaddress
Syntax DELete OSPF SUMMaryaddress=ipadd
The summaryaddress parameter specifies the IP prefix that defines a range of
routes to no longer summarise.
set ospf summaryaddress
Syntax SET OSPF SUMMaryaddress=ipadd MASK=ipadd
[ADVertise={ON|OFF|YES|NO|True|False}] [TAG=0..65535]
