I am not entirely sure without having the topology and full config but "show route" on the EX4600 will show you where traffic will be forwarded.

The next hop ip address is in the new juniper lan and works
I guess that is where I went wrong
The cisco core that I am replacing has a 0.0.0.0/0 route to the firewall, so the next step of PoC is to create the firewall Vlan and put the next-hop to be the firewall?

I am still trying to figure this out.
I was able to change the ip address of management set to irb to a new Juniper vlan by changing the next-hop.
Confused as the next hop was in the cisco core management vlan.

Hi!
I have a problem on my EX4600 that I cannot get my head around.
I was trying to change my management vlan (same as cisco mgmt ) to another new subnet (juniper mgmt)
Initially I assigned
irb.0 family inet address <ip from cisco mgmt>
Created vlan and assigned to interface this to vlan
Switches
vlan-id 911;
l3-interface irb.0;
I then created a Juniper Management vlan and assigned it to irb.999
Juniper Management
vlan-id 999;
l3-interface irb.999;
show interfaces irb.999
family inet {
address 172.22.73.129/27;
}
The interface out is
show interfaces xe-0/0/0
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members all;
}
storm-control default;
}
}
I can ping and web manage the ip address of the switch on the Juniper vlan
If I try to change irb.0 to a different ip address in the juniper vlan or delete irb.0 or remove irb.0 from the cisco management vlan I cannot get any traffic on either ip address.
I totally get this is odd, I blame it on the shortages in network equipment!
show interfaces xe-0/0/0
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members all;
}
storm-control default;
}
{master:0}[edit]
JCore# show interfaces irb
unit 0 {
family inet {
address <ip1>;
}
}
unit 303 {
family inet;
}
unit 999 {
family inet {
address <ip2>;
}
}
{master:0}[edit]
JCore# show vlans Management
vlan-id 999;
l3-interface irb.999;
{master:0}[edit]
JCore# show vlans Switches
vlan-id 911;
l3-interface irb.0;
Many Thanks!
