# How to configure right value of delay.

When somebody says to configure delay 200 while redistributing routes in ospf, we'll divide it by 10, like in this case

200/10 = 20 and if somebody asks us to configure Delay as 5ms then

In this case delay will be 5,000/10 i guess and it would be 500

am i right? please anybody define this concept?

THe delay value is in microseconds.  There are 10 microseconds in a millisecond.  Right idea, wrong direction....   Multiply by 10.

Aloha Usman Ali ****,

In regards to your post on "How to configure right value of delay?":

First some clarification:

Delay = (sum of all outgoing interfaces in micro-seconds) / 10

When entering the delay portion of the five seed metric under the Redistribution command, enter the delay as 10s of micro-seconds.  So, if you what the delay to be 5000 micro-seconds, enter 500.  Here is an example:

router eigrp 5
redistribute rip metric 10000 500 255 1 1500

Please note the enteries above, BW (K1) = 10000, delay (K3)= 500, reliability (K4) = 255, load (K2) = 1 and MTU (K5) = 1500.  Also these are not in order K1 - K5.  You can verify the seed metric values using the "show ip eigrp top x.x.x.x" command.  Here is the output from my example:

GW.BTSC.R1#sh ip eigrp top 192.168.61.0
IP-EIGRP (AS 5): Topology entry for 192.168.61.0/24
State is Passive, Query origin flag is 1, 1 Successor(s), FD is 1503
Routing Descriptor Blocks:
0.0.0.0, from Redistributed, Send flag is 0x0
Composite metric is (1503/0), Route is External
Vector metric:
Minimum bandwidth is 10000 Kbit
Total delay is 5000 microseconds
Reliability is 255/255
Minimum MTU is 1500
Hop count is 0
External data:
Originating router is 192.168.61.50 (this system)
AS number of route is 0
External protocol is RIP, external metric is 0
