Hi,

I understand you are talking about the default route, not 124 network?

Are you sure the  prefix-lists DEFAULT is matching it?

And the route-map AIR is applied correctly?

If yes, have you tried

clear ip bgp * soft

on your router?

HTH,

Milan

ip prefix-list DEFAULT: 1 entries

   seq 5 permit 0.0.0.0/0

Hi,

it seems route-map DEFAULT-PRY-SIF is applied on the default route prefix received, not route-map AIR-IN.

Can you paste the config part where you are applying the route maps?

HTH,

Milan

[prashantrecon]

yA route-map DEFAULT-PRY-SIF is applied on the default route prefix BUT WHEN ever SIF goes down .route-map AIR-IN

will be used .so when i excute show ip bgp when SIF goes down  local prefernce value for AIR is not displayed.

[milan.kulik]

Hi,

I believe the  route-map AIR-IN might not be applied for some reason.

Otherwise you should see LP 300 in ypur original output.

HTH,

Milan

Hi

It is applied when i shutdown interface to which SIF is applied than traffic is going through AIR_IN routemap

Hi Milan,

Thank Milan fot u help

Hi Prashant,

Do you have any other route-map entry with lower seq number which already matches the default route?

Did you apply the route map to the other neigbor (124.x.x.x) to in direction?

Did you try clear ip bgp with this neigbor?

Hope that helps,

Vasilis
