Configuring ranges on an ABR to reduce advertising to the backbone
For more information, see “About configuring ranges on an ABR to reduce advertising to the
backbone” (page 259).
Syntax:
router ospf3 area [ ospf3-area-id | backbone ]
range ipv6-addr/prefix [ type | [ summary [ cost 1 - 16777215 ]] |
inter-area | nssa ] [ no-advertise ]
Syntax:
[no] router ospf3 area [ ospf3-area-id | backbone ]
range ipv6-addr/prefix [ type | [ summary [ cost 1 - 16777215 ]] |
inter-area | nssa ]
Use this command on a routing switch intended to operate as an ABR for the
specified area to do either of the following:
• Simultaneously create the area and corresponding range setting for routes to
summarize or block.
• For an existing area, specify a range setting for routes to summarize or block
(prevent).
ospf3-area-id
Same area ID as in “Configuring an OSPFv3 backbone or normal area”
(page 211), except you cannot use a backbone area number (0 or 0.0.0.0) for
a stub area or NSSA.
range ipv6-addr/prefix
Defines the range of RAs to either summarize for injection into the backbone
area or to prevent from being injected into the backbone area.
The ipv6-addr value specifies the IPv6 address portion of the range, and
prefix specifies the leftmost significant bits in the address.
The ABR for the specified area compares the IPv6 address of each outbound
RA with the address and significant bits in the mask to determine which routes
to select for either summarizing or blocking.
