Routing

I have a policy-statement in a configuration example that shows:

inactive: route-filter 10.0.0.0/8 longer;

What does inactive: do in this case.?

Thank you

Hi,

It indicates that the operator wants this route-filter in a disabled mode. This is usually done where you want the configs in place but it shouldn't effect in anyways and later you can decide to activate the same to get its effect.

Say for example, from BGP-EXPORT policy as below:

suryak@PE# show policy-options
policy-statement BGP-PEER1 {
    term a {
        from {
            route-filter 10.0.0.0/8 orlonger;
            route-filter 20.0.0.0/8 orlonger;
        }
        then accept;
    }
}

Now for some administrative purpose, I decide that routes within 10/8 ranges shouldn't be advertised to BGP Peer. Now instead of deleting the route-filter I decide to deactivate which as good as it is not there. By doing this, I can get 10/8 routes re-advertised again by just activating the route-filter

suryak@PE# deactivate policy-options policy-statement BGP-PEER1 term a from route-filter 10/8 orlonger

suryak@PE# show policy-options
policy-statement BGP-PEER1 {
    term a {
        from {
            inactive: route-filter 10.0.0.0/8 orlonger;
            route-filter 20.0.0.0/8 orlonger;
        }
        then accept;
    }
}

That is what I thought. I just needed to be sure.

Thanks again
