Thanks,
the source address is 10.0.0.18.
But any device within the vlan-400 cannot ping the loopback. Such as 10.0.0.17, .15, .19, etc.
They are all connected to the switch.
In particular 10.0.0.18 is connect to port ge-0/0/11.
robmin@ex2200c# show interfaces ge-0/0/11
unit 0 {
family ethernet-switching {
port-mode access;
}
}
All of the ports that are connecting these devices are using the same configuration of port-mode access.
And these ports are attached to the vlan-400 as follows:
vlan-400 {
interface {
ge-0/1/0.0;
ge-0/0/2.0;
ge-0/0/7.0;
ge-0/0/10.0;
ge-0/0/11.0; <<<-------- 10.0.0.18
ge-0/0/3.0;
ge-0/0/0.0;
ge-0/0/1.0; <<<------- this is the port that the cable modem is connected to, it is also port-mode access.
}
l3-interface vlan.400;
}
The default gateway for 10.0.0.18 is 10.0.0.26, but other devices still have the default gateway as 10.0.0.1 (the cable modem) in either case the switch's loopback is not pingable.
10.0.0.26 is configured under:
show interfaces vlan
...
}
unit 400 {
family inet {
address 10.0.0.26/24;
}
}
AND
the loopback is configured as follows:
robmin@ex2200c# show interfaces lo0
unit 0 {
family inet {
address 10.0.0.14/24;
}
}
Security zones are not possible to configure on an ex2200-c and I tried turning of igmp-snooping which currently is set for all vlans.
Thanks very much,
robin
