Redistribute a route with another metric on EIGRP

[Netadmins_BNPP2K10]

Hi All,

Actually, the main idea it's advertise a subnet with another metric to WAN link.

So, we've created the script below, but it didn't work. It has done on 4948 switch with 122-54.SG version and EIGRP protocol.

Obs.: This subnet 10.11.99.0/26 is announced by another switch.

sh ip eigrp topology 10.11.99.0/26

Hi,

I had the same problem some days  ago. I found out, that it seems to be only possible to increase the metric, not to decrease the metric.

You can increase the Bandwidth, the Delay, the Load and the Reliability, but you cannot change the RD directly.

Maybe they did for reasons of loop prevention...

Hello

What actually are you trying to accomplish - unequal load sharing - if so this can be acheived by eigrp compositic metric calculations which you can in fact apply a load share value you wish?

Hi Paul,

I was trying redistribute the route with a worse metric.

[paul driver]

Hello

So to have a preffered route or to load share with a definative value?

Hello

Apologies I am still unclear what you’re trying to establish - however looking at the diagram you posted

Remote site:
1)
 to prefer a certain path for a specific network can be accomplish by  a distance command relating to a ACL for the preferred prefix.

2) If you wish to do this for all traffic then the distance or delay command can accomplish this

Data centre perspective:
you can utilize eigrp compostic metrics for unequal load sharing for all traffic

or

Possibly if applicale summarise the prefix from either DC and then leak the more specific route from preferred DC

Please, take a look the attached file.

I would like to redistribute it on DC1 with a worse metric to become the Wan in DC 2 like active.
