EIGRP with offsetlist and route-map

Unanswered Question

Dear All,

I like to change the EIGRP delay metric for a route (example:150.101.1.0)

I find two options

1. using route-map & set metric along with distribution-list inside router eigrp

2. offset-list

I see both are similar. Is it so,? Which one I have to use for this scenario.


Also In lab environment i noticed one behaviour of these commands.

when configuring "route-map & set metric used along with distribution-list "

I am able to manipulate only bandwidth parameter, But changing delay parameter is of no use

when configuring "offset-list"

By setting the offset value, delay parameter is changed accordingly.

Please expalain the actual usage of these two tricks to change the metric of the route

Thanks in advance

Hello R.B. Kumar,


when you use a route-map with the distribute-list command you can set the metric with

set metric bw1 delay reliability load mtu


inside the route-map


this should become the new metric for the route so the effect is not additive as the offset-list but it should be a replacement


I mean something like the following:


route-map red_stat permit 10

match ip address 10

set metric 2048 2000 255 255 1500

!

route-map red_stat permit 20

match ip address 20

set metric 2048 2000 255 255 1500

!

route-map red_stat permit 30

match ip address 30

set metric 2048 2000 255 255 1500

!



Hope to help

Giuseppe

Hi Giuseppe,


Awesome answer (offset is additive & route-map with distribution-list is changes to new metric), which I have never seen so far. Thank you very much


Can you also explain me why I am not able to modify delay parameter using the commands as below?


route-map test permit 10

match ip address

set metric 1544 3500 255 1 1500 (I am changing delay parameter to 3500)


But where are as using offset-list I am able to do this. Is this the actual behavior or I am doing any mistake here

Hello R.B. Kumar,

may you post examples using


sh ip eigrp topology


of the two results you get ?


This can help the discussion
