BGP RIB-failure (17)

[gueyekhadija10]

Hello,

I wanted an explanation of the problem of BGP RIB-failure on a default route 0.0.0.0

I wanted to know how to solve this problem and what can cause this?

Thanks,

Hello,

RIB-failure occurs when your default-router-learned by BGP has a higher administrative distance

that another default-route learned by other routing source. Check your routing table.

Hello,

I look at my routing table and I have a default route.

S* 0.0.0.0/0 [1/0] via  adrIPGateway

In this case what should I do because I have two same route with different administrative distances?

Thanks,

If you prefer BGP change default route administrative distance:

ip route 0.0.0.0 0.0.0.0

<1-255>    Distance metric for this route

I suppose that your BGP default-route is learned by eBGP (administrative distance 20).

So if you set your static default route to an administrative distance higher than 20, the BGP default router

will be installed on routing table. If sometime the BGP default-route disppear then the static router willl be

applied.

Hello,

I agree with Antonio,

If you really in an need of putting your BGP default route in the routing table, and the static as you back up then,

ip route 0.0.0.0 0.0.0.0 30 (If you have learned it form EBGP Neighbor)

now you might get a route

B*   0.0.0.0/0 [20/0] via 15.1.1.1, 00:00:49

I have highleted the AD value of EBGProute for your conviniene.
