assitance with vlans and EX switches

    Hi community.

    I need some help here.

    Trying to move from a layer 2 physically segmented network to a layer 3 routed network with VLANS.

    I have a number of juniper EX switches connected and a watchguard firewall currently acting as my bridge between the physical networks.

    For expansion reasons I need to move into VLANs and making this a bit more complex.

    For the time being, I cant cut over all at once, so I need my switches to function as is until I flip certain ports to vlan assignments.

    router/firewall has interface IP from switch A ge/0/0/0 10.0.0.1 interface ip

    I cant seem to get connectivity from Switch A (console) to ssh to Switch B. I cant seem to ping across to the default gateway from Switch B to Switch A and get to the gw ip.

    Thanks for the assistance here. let me know if more detail or configurations are needed.

    Switch A

    vlans 10 production (10.0.0.0/24)
    vlan 101 cameras (10.0.0.1.0/24)
    port 47 - uplink to switch A (trunk mode)
    port 0 - uplink to watchguard firewall/router
    switch In band management at 10.0.0.250

    interfaces {

    ge-0/0/0 {

    description "uplink to watchguard";

    unit 0 {

    family ethernet-switching;

    }

    }

    ge-0/0/47 {

    description "uplink to gs728tp";

    unit 0 {

    family ethernet-switching {

    port-mode trunk;

    vlan {

    members all;

    }

    native-vlan-id 10;

    }

    }

    }

    me0 {

    disable;

    unit 0 {

    family inet;

    }

    }

    vlan {

    unit 0 {

    family inet {

    address 10.0.0.250/24;

    }

    }

    }

    }

    routing-options {

    static {

    route 0.0.0.0/0 next-hop 10.0.0.1;

    }

    }

    Switch B

    vlans 10 production (10.0.0.0/24)
    vlan 101 cameras (10.0.0.1.0/24)
    trunk port 47 - uplink to switch A
    switch In band management at 10.0.0.252

    interfaces {

    ge-0/0/0 {

    unit 0 {

    family ethernet-switching {

    port-mode access;

    vlan {

    members cameras;

    }

    }

    }

    }

    ge-0/0/47 {

    unit 0 {

    family ethernet-switching {

    port-mode trunk;

    vlan {

    members all;

    }

    native-vlan-id 10;

    }

    }

    }

    irb {

    unit 10 {

    family inet;

    }

    }

    me0 {

    disable;

    unit 0 {

    family inet;

    }

    }

    vlan {

    unit 0 {

    family inet;

    }

    unit 10 {

    family inet {

    address 10.0.0.252/24;

    }

    }

    unit 101 {

    family inet;

    }

    }

    }

    vlans {

    cameras {

    vlan-id 101;

    }

    default;

    production {

    vlan-id 10;

    l3-interface vlan.10;

    }

    }

    When I run show lldp neighbors from switch B - i can see the interface of switch A - but when I do this from Switch A, I do not see the LLDP neighbor for Switch B.
