Redistribute static route in eigrp with VRF

[Joris Deprouw]

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

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

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
