Redistribute static route in eigrp with VRF

Hi all,

I have an issue with my setup of a 6500 switch (12.2(33)SXI9).

We have a 6500 switch with several VRF's. For a certain VRF I would like to redistribute a static route in EIGRP. After doing so I don't see the static route on my eigrp neighbor.

This is a overview of my config. I'm basically redistributing only my static route for this vrf in eigrp.

I found a similar case in which the solution was adding a metric to the static route. (eg. redistribute static route-map static-eigrp-pp metric 10000 100 255 1 1500). But the strange thing is that we don't have this issue on a similar machine (same IOS, same config setup).

Any help appreciated...

Thanks,

Best Regards,

Joris

Redistribute static route in eigrp with VRF

Hello Joris,

the feasible distance looks like "infinite" in the 32 bit metric field

>>State is Passive, Query origin flag is 1, 0 Successor(s), FD is 4294967295

I would say for this reason the route is not advertised to the EIGRP neighbor.

the use of a seed metric expressed in the 5 metric components may help

Hope to help

Re: Redistribute static route in eigrp with VRF

Hi Giuseppe,

Maybe I didn't explain everything correctly.

In total we have 4 routers.

Router A and B have the same static route configured for vrf TEST.

Router A and B have the same EIGRP AS number with a redistribute static in it.(same config as above)

I guess it is normal they don't see the redistributed static route of eachother since the have the static route configured themselves which has a lower Administrative Distance than the EIGRP redistributed route.

Is that correct?

Now Router C and D are also in the EIGRP 20 group and receive the static route by EIGRP (redistributed by A and B).

The thing is now, C and D only receive it from router B not from router A.

It could well be this is normal behavior, but how does router C and D decide which route will be placed in the routing tabel, since they receive it from both A and B.

If this is normal behavior, both C and D should receive the static route from router A the moment we delete the static route from the config of router B. Is it correct to asume that?

Best Regards,

Joris
