Thank you for the explanation about directly connected routes. So I TOOK OUT the two static
routes, 10.0.0.0/24 next-hop 10.0.0.26 and, 10.0.0.240 next-hop 10.0.0.26.
robmin@ex2200c# show routing-options
static {
route 0.0.0.0/0 next-hop 10.0.0.1;
route 240.0.0.8/32 discard;
route 240.0.0.9/32 reject;
route 1.1.1.1/32 {
next-hop 10.40.1.1;
qualified-next-hop 2.2.2.2 {
preference 7;
}
}
route 7.7.7.7/32 next-hop 10.20.1.3;
route 18.18.18.18/32 next-hop 10.80.1.1;
route 6.6.6.6/32 next-hop 10.60.1.1;
route 10.60.31.0/24 next-hop 10.60.1.1;
I had already added this as you asked me to on your previous post.
robmin@ex2200c# show interfaces lo0
unit 0 {
family inet {
address 10.0.0.4/32; <<<---- This was the 10.0.0.240, I changed it just now to 10.0.0.4 in all the places it occured.
By The Way, you suggested: Change lo0 to use a /32 and, assuming your default gateway is set correctly on your NMS, you should be able to reach both. How can a ping get a response with the /32, doesn't it have to be a /24 like everything else on the network to talk to devices. In Other workds, doesn't a /24 put it on the same subnet? Don't devices have to be in the same subnet (vlan) inorder to ping each other? Wouldn't this make it so the ping can't get to the lo0 interface?

EX2200-c Switch, 10.0.0.4 on lo0 (changed from .240 to .4) still can't be pinged from outside the
switch.

Junipter J2350 router connected directly to ge-0/0/1, turned off since I haven't configured the
router yet.
Cisco 1841 router directly connected to ge-0/0/0, also turned off for now
I just grabbed these two devices from my CCIE lab today.
All of these computers, servers and devices are connected to the EX2200-c switch on ports in the
vlan-400. The switch can ping everyone of them except my Windows Server 2008 R2 on
10.0.0.17 and and ubuntu physical and virtual machines .7, .8. very very ODD.
All other nodes can ping all addresses except the lo0, 10.0.0.4.
Parallels Virtual Machine Guest OS Windows 7 Professional on MacBook Air, 10.0.0.3
MacBook Air, 10.0.0.2
Cannot ping the lo0 address of 10.0.0.4 from any device plugged into a port on the Switch.
