asr 9006 bgp network advertisement problem null0 routes

Hi,

I want to ask a question cisco experts. I have couple of cisco asr 9006. I have to reload with cef problem after then reload I saw didn't advertise ip blocks my router.

I checked the configuration then I saw 2a02:ac80::/32 Null0 240 the configs are correct.

I could remove the config no 2a02:ac80::/32 Null0 240 after that wrote config again 2a02:ac80::/32 2a02:ac80::1 after then start to advertisement.

What can I wrong?

I know IOS bgp advertisement. Have to ip blocks per null0 routes. What different IOS and XR?

Hi,

Looks like you redistribute static route into BGP. Do you have other static routes other than the route you mentioned above? If yes, did they have same problem too? In term of BGP advertisement, there is no difference between IOS and XR.

thanks,
