VPRN Service Configuration Commands
Page 1088 7750 SR OS Services Guide
Description This command adds the passive property to the OSPF interface where passive interfaces are
advertised as OSPF interfaces but do not run the OSPF protocol.
By default, only interface addresses that are configured for OSPF will be advertised as OSPF
interfaces. The passive parameter allows an interface to be advertised as an OSPF interface without
running the OSPF protocol.
While in passive mode, the interface will ignore ingress OSPF protocol packets and not transmit any
OSPF protocol packets.
The no form of the command removes the passive property from the OSPF interface.
Default Service interfaces defined in config>router>service-prefix are passive.
All other interfaces are not passive.
priority
Syntax priority number
no priority
Context config>service>vprn>ospf>area>interface
Description This command configures the priority of the OSPF interface that is used an election of the designated
router on on the subnet.
This parameter is only used if the interface is of type broadcast. The router with the highest priority
interface becomes the designated router. A router with priority 0 is not eligible to be Designated
Router or Backup Designated Router.
The no form of the command reverts the interface priority to the default value.
Default priority 1
Parameters number — The interface priority expressed as a decimal integer. A value of 0 indicates the router is
not eligible to be the Designated Router of Backup Designated Router on the interface subnet.
Values 0 — 255
retransmit-interval
Syntax retransmit-interval seconds
no retransmit-interval
Context config>service>vprn>ospf>area>interface
config>service>vprn>ospf>area>virtual-link
Description This command specifies the length of time, in seconds, that OSPF will wait before retransmitting an
unacknowledged link state advertisement (LSA) to an OSPF neighbor.
The value should be longer than the expected round trip delay between any two routers on the
attached network. Once the retransmit-interval expires and no acknowledgement has been received,
the LSA will be retransmitted.
The no form of this command reverts to the default interval.
