[j-nsp] bgp policy

[Raheel Muhammad]

Hi,

term term-1 {
    from {
        route-filter x.x.128.0/19 upto /24;
    }
    then accept;
}
term ios-implicit-deny {
    then reject;
}

This way x.x.150.0/23 is not getting advertised though it fall in between. I
have to add 150.0/23 specifically. But if i am putting this policy

term term-1 {
    from {
        route-filter x.x.144.0/20 upto /24;     or x.x.152.0/21/24 upto /24;
    }
    then accept;
}
term ios-implicit-deny {
    then reject;
}

Then x.x.150.0/23 is getting advertised without allowing it specifically.


raheel at xxx-M10i# run show route receive-protocol bgp x.x.242.249

* x.x.150.0/23         x.x242.249      0       100        xxx22 I


I am receiving this prefix from customer.

Regards


Thanks
