tag tag
: Specifies a tag value for the summary route, used by a routing policy to control summary
route advertisement, in the range of 0 to 4294967295. The default is 1.
Description
Use
asbr-summary
to configure a summary route.
Use
undo asbr-summary
to remove a summary route.
No ASBR route summarization is configured by default.
With the
asbr-summary
command configured, an ASBR summarizes redistributed routes that fall
into the specified address range into a single route. If the ASBR resides in an NSSA area, it
advertises the summary route in a Type-7 LSA into the area.
With the
asbr-summary
command configured, an NSSA ABR summarizes routes described by
Type-5 LSAs translated from Type-7 LSAs into a single route and advertises the summary route to
other areas. This command does not take effect on non NSSA ABRs.
If the
undo asbr-summary
command is used, summarized routes will be advertised.
