Virtual Private Routed Network Services
7210 SAS-X OS Services Guide Page 841
Default reference-bandwidth 100000000 — Reference bandwidth of 100 Gbps.
Parameters reference-bandwidth — The reference bandwidth in kilobits per second expressed as a decimal
integer.
Values 1 — 1000000000
super-backbone
Syntax [no] super-backbone
Context config>service>vprn>ospf
Description This command specifies whether CE-PE functionality is required or not. The OSPF super backbone
indicates the type of the LSA generated as a result of routes redistributed into OSPF. When enabled,
the redistributed routes are injected as summary, external or NSSA LSAs. When disabled, the
redistributed routes are injected as either external or NSSA LSAs only.
Default no super-backbone
suppress-dn-bit
Syntax [no] suppress-dn-bit
Context config>service>vprn>ospf
Description This command specifies whether to suppress the setting of the DN bit for OSPF LSA packets
generated by this instance of OSPF on the router. When enabled, the DN bit for OSPF LSA packets
generated by this instance of the OSPF router will not be set. When disabled, this instance of the
OSPF router will follow the normal proceedure to determine whether to set the DN bit.
Default no suppress-dn-bit
timers
Syntax timers
Context config>service>vprn>ospf
Description This command enables the context that allows for the configuration of OSPF timers. Timers control
the delay between receipt of a link state advertisement (LSA) requiring a Dijkstra (Shortest Path First
(SPF)) calculation and the minimum time between successive SPF calculations.
Changing the timers affect CPU utilization and network reconvergence times. Lower values reduce
convergence time but increase CPU utilization. Higher values reduce CPU utilization but increase
reconvergence time.
Default none
