Redistribute Static under EIGRP Process

[GRANT3779]

Hi Folks,

I seem to be having a hard time finding an official answer to this.

When redistributing statics into EIGRP (just "redistribute static"), no route-maps, no stating any metrics, no default metrics.

What metrics are used when the route does get redistributed? I have read it is the K Values of the Outgoing Interface specified for the specific static route. Is this indeed correct? I will test tonight but just wanted to some clarification.

Thanks

Hello Grant,

yes it looks like that EIGRP is able to redistribute static routes without configuring a seed metric and that the seed metric is taken from the outgoing interface parameters (delay and BW) of the static route.

see this older thread

https://community.cisco.com/t5/routing/redistributing-static-routes-to-eigrp/td-p/627225

Really interesting I always set the seed metric manually when redistributing into EIGRP.

Hope to help

Hi @GRANT3779 ,

Maybe this guide can give you some help:

@GRANT3779  hello,

Note that there are 5 metrics that must be specified when we redistribute static route into EIGRP in Cisco IOS router – and this applies when we redistribute other routing protocol into EIGRP as well. This because EIGRP is a smart routing protocol that consider all these aspectswhen creating a route entry. The mentioned metrics are:

• Bandwidth: Specify the bandwidth value of the link here in Kbits per second – this doesn’t have to be the actual condition and it has nothing to do with the real bandwidth, as this is only for reference used by EIGRP to calculate the final metric.
• Delay: Specify the delay value here in 10 microseconds unit – again, this is only for reference used by EIGRP to calculate its metric.
• Reliability: Specify value here between 0-255 where 255 means EIGRP will see the link with maximum reliability
• Load: Specify value here between 1-255 where 255 means EIGRP will see the link as 100% loaded
• MTU: Specify the MTU value between 1-65535, normally it is 1500 but depending on the applications running in the network you might want to adjust this value. However, this does not change the actual MTU of the link.

The static routes are like directly connected interfaces, even if your issuing the command redistribute static, only AD will be changed as it will be advertise as an external network

Also whenever you will advertise this network to other eigrp neighbors it will use the interface parameters to calculate the bandwidth where its neighbour is connected.
