Ipv6 Ospf Transmit-Delay - Edge-Core AS6700-32X Cli Reference Manual

ipv6 ospf transmit-
delay
Default Setting
5 seconds
Command Usage
◆
A router will resend an LSA to a neighbor if it receives no acknowledgment after
the specified retransmit interval. The retransmit interval should be set to a
conservative value that provides an adequate flow of routing information, but
does not produce unnecessary protocol traffic. Note that this value should be
larger for virtual links.
◆
Set this interval to a value that is greater than the round-trip delay between any
two routers on the attached network to avoid unnecessary retransmissions.
Example
Console(config)#interface vlan 1
Console(config-if)#ipv6 ospf retransmit-interval 7
Console(config-if)#
This command sets the estimated time to send a link-state update packet over an
interface. Use the no form to restore the default value.
Syntax
ipv6 ospf transmit-delay seconds [instance-id instance-id]
no ipv6 ospf transmit-delay [instance-id instance-id]
seconds - Sets the estimated time required to send a link-state update.
(Range: 1-65535)
instance-id - Identifies a specific OSPFv3 routing process on the link-local
network segment attached to this interface. (Range: 0-255)
Command Mode
Interface Configuration (VLAN)
Default Setting
1 second
Command Usage
◆
LSAs have their age incremented by this delay before transmission. When
estimating the transmit delay, consider both the transmission and propagation
delays for an interface. Set the transmit delay according to link speed, using
larger values for lower-speed links.
◆
If this delay is not added, the time required to transmit an LSA over the link is
not taken into consideration by the routing process. On slow links, the router
may send packets more quickly than devices can receive them. To avoid this
