radvd

I configured a network using radvd.conf in the network gateway, everything it's working well.

The problem: When I stop the radvd process the default gateway of all machine is removed instantaneously. When this occur the whole network is not working - all hosts in the network stop. In my point of view this is a big problem that I could not solve yet.

My question: Is there some way for the default gateway do not be removed when radvd process is stoped or there is some other issue involving it? Please could you help me?

I have tried this options, but did not solve the problem.

• AdvRouteLifetime infinity;

• AdvRoutePreference medium;

• RemoveRoute off;

For more details, below the radvd.conf. The daemon version is: 2.17

interface enp0s3 { AdvSendAdvert on; AdvLinkMTU 1480; prefix fd4d:XXXX:XXXX:XXXX:a00:27ff:fe5e:7248/64 { DeprecatePrefix on; AdvOnLink on; AdvAutonomous on; AdvRouterAddr on; };

    RDNSS 2001:4860:4860::8888 2001:4860:4860::8844 {
    FlushRDNSS off;
    };

    DNSSL t1.com {
    FlushDNSSL off;
    };

    route ::/0 {
    AdvRouteLifetime infinity;
    AdvRoutePreference medium;
    RemoveRoute on;
    };

};

Thanks in advance!

GOD bless you!!!

The radvd.conf below has RemoveRoute on. Is this the current config of the gateway?

Actually this is the actual configuration, but I had tried "RemoveRoute off;" too, but the result is the same.

Closing this stale issue.
