Can't Ping Internal IRB

Hello All,

I'm new to Juniper and need some assistance. Current situation, we are in the process of migrating our cisco infrastructure to Juniper. Our ex4300 will serve as our core switches. After some research, I was able to create a  IRB (server as management) with an ip address and link it to my L2 vlan. When I try ping internally on the switch, I'm getting no route to host.  With cisco, you didn't have to put routes in unless you were a downstream and that was a default gateway. 

Currently, trying to build out a lab network before the migration...just fyi, so I'm wide open to suggestions

Config Excerpt:

irb {
unit 4 {
family inet {
address 10.10.10.1/24;
}
}
}

vlans {
Management {
vlan-id 4;
l3-interface irb.4;
}
default {
vlan-id 1;
}

Error:
