Multi-home BGP

KenPaul

Hello,

We have internet connection from 2 providers coming into ATP800. We have our own class C that we are pushing to both providers. Both providers see the class C but ATP800 is also pushing prefixes from other provider. How can we prevent this?

Thanks,
Ken

Do you mean the ATP800 establishes two BGP routes to two providers and you don't want those two providers doesn't know each other's routing information? As below:
ATP800 to push BGP info(without provider B's routing info, only ATP800's) to provider A.
ATP800 to push BGP info(without provider A's routing info, only ATP800's) to provider B.

Hi MJStar,

Sorry for the delay. Correct. ATP800 should only push the IP setup on ATP. Currently, it pushes routes from Provider A to Provider B and vice versa.

Hi @KenPaul

Currently, we don’t support this feature.

ATP800 would share BGP routing info to other two sites.

Although Zyxel does not support the feature,
If provider A, B support route-map . You can use it to restrict the Route table which learned from other BGP member.
I have the same issue before. It would work .
