external 1 - 255
Changes the administrative distance for routes between the OSPFv3 domain
and other EGP domains.
inter-area 1 - 255
Changes the administrative distance for routes between areas within the same
OSPFv3 domain.
intra-area 1 - 255
Changes the administrative distance for routes within OSPFv3 areas.
Default: 110; Range: 1 - 255
Enforcing strict LSA operation for graceful restart helper mode
For more information, see “About enforcing strict LSA operation for graceful restart helper mode
(optional)” (page 259).
Syntax:
[no] restart strict-lsa
Used in the OSPFv3 context to enable or disable strict LSA operation in a network
segment for a neighboring router that is attempting a graceful restart.
When enabled, this operation halts helper mode support if a change in LSAs
(topology change) is detected during the restart period of the neighbor.
Default: Strict LSA operation enabled
The no form disables strict LSA operation.
Adjusting performance by changing the VLAN interface settings
Cost per interface
Syntax:
ipv6 ospf3 cost 1 - 65535
Used in the VLAN context to indicate the overhead required to send a packet across
an interface. You can modify the cost to differentiate between 100 Mbps and 1000
Mbps (1 Gbps) links.
This command assigns the specified cost to all networks configured on the VLAN.
Default: 1
Dead interval per interface
Syntax:
ipv6 ospf3 dead-interval 1 - 65535
Used in the VLAN context to indicate the number of seconds that a neighbor router
waits for a hello packet from the specified interface before declaring the interface
"down".
This command assigns the specified dead interval to all networks configured on the
VLAN.
Default: 40 seconds
