Hi,
Does anyone has ever tried to use the build-in Junos DHCP server into other
routing-instance.
Here's the conf statement:
system {
        dhcp {
            traceoptions {
                file dhcp_debug.log size 5m files 10;
                level all;
                flag all;
            }
            pool 192.168.1.0/24 {
                address-range low 192.168.1.10 high 192.168.1.20;
                router {
                    192.168.1.1;
                }
            }
            pool 192.168.2.0/24 {
                address-range low 192.168.2.10 high 192.168.2.20;
                router {
                    192.168.2.1;
                }
            }
        }
    }
interfaces {
    fe-0/0/0 {
        unit 0 {
            family inet {
                address 192.168.254.15/24;
            }
        }
    }
    fe-0/0/1 {
        unit 0 {
            family inet {
                address 192.168.254.100/24;
            }
        }
    }
    fe-0/0/2 {
        unit 0 {
            family inet {
                address 192.168.1.1/24;
            }
        }
    }
    fe-0/0/3 {
        unit 0 {
            family inet {
                address 192.168.254.200/24;
            }
        }
    }
    fe-0/0/4 {
        unit 0 {
            family inet {
                address 192.168.2.1/24;
            }
        }
    }
    lo0 {
        unit 0 {
            family inet {
                address 10.10.10.1/32;
            }
        }
    }
}
routing-instances {
    isp1 {
        instance-type virtual-router;
        interface fe-0/0/1.0;
        interface fe-0/0/2.0;
        routing-options {
            static {
                route 0.0.0.0/0 next-hop 192.168.254.1;
            }
        }
    }
    isp2 {
        instance-type virtual-router;
        interface fe-0/0/3.0;
        interface fe-0/0/4.0;
        routing-options {
            static {
                route 0.0.0.0/0 next-hop 192.168.254.1;
            }
        }
    }
}


And here is the result:
Oct 22 21:45:32 changed ifd fe-0/0/2 to down
Oct 22 21:45:34 rtsock ifd message for fe-0/0/2
Oct 22 21:45:34 changed ifd fe-0/0/2 to up

Oct 22 21:45:39 received packet from 0.0.0.0 port 68 interface fe-0/0/2.0

Oct 22 21:45:39 packet from 0.0.0.0 discarded: not default routing instance
Oct 22 21:45:42 received packet from 0.0.0.0 port 68 interface fe-0/0/2.0
routing instance isp1
Oct 22 21:45:42 packet from 0.0.0.0 discarded: not default routing instance


Seems that DHCP server is working only in default routing-instance, but this
is not stated anywhere.
Asking here first, then preparing to raise case in JTAC
