OSPF
config ospf area <areaid> nssa [summary |
nosummary] stub-default-cost <cost>
{translate}
Configures an OSPF area as a NSSA.
config ospf area <areaid> stub [summary |
nosummary] stub-default-cost <cost>
Configures an OSPF area as a stub area.
config ospf asbr-filter [<access_profile> | none] Configures a route filter for non-OSPF routes
exported into OSPF. If none is specified, no
RIP and static routes are filtered.
config ospf ase-summary add <ipaddress>
<mask> cost <cost> {<tag_number>}
Configures an aggregated OSPF external route
using the IP addresses specified.
config ospf ase-summary delete <ipaddress>
<mask>
Deletes an aggregated OSPF external route.
config ospf delete virtual-link <routerid>
<areaid>
Removes a virtual link.
config ospf delete vlan [<name> | all] Disables OSPF on one or all VLANs (router
interfaces).
config ospf direct-filter [<access_profile> |
none]
Configures a route filter for direct routes. If
none is specified, all direct routes are exported
if ospf export direct is enabled.
config ospf lsa-batching-timer <timer_value> Configures the OSPF LSA batching timer
value. The range is between 0 (disabled) and
600 seconds, using multiples of 5 seconds.
The LSAs added to the LSDB during the
interval are batched together for refresh or
timeout. The default setting is 30 seconds.
config ospf metric-table <10M_cost>
<100M_cost> <1G_cost>
Configures the automatic interface costs for 10
Mbps, 100 Mbps, and 1 Gbps interfaces. The
default cost for 10 Mbps is 10, for 100 Mbps is
5, and for 1 Gbps is 1.
config ospf originate-default {always} cost
<metric> [ase-type-1 | ase-type-2] {tag
<number>}
Configures a default external LSA to be
generated by OSPF, if no other default route is
originated by OSPF by way of RIP and static
route re-distribution. If always is specified,
OSPF always advertises the default route. If
always is not specified, OSPF adds the
default LSA if there is a reachable default route
in the route table.
config ospf routerid [automatic | <routerid>] Configures the OSPF router ID. If automatic is
specified, the switch uses the largest IP
interface address as the OSPF router ID. The
default setting is automatic.
