Juniper re-learnings (OSFv3, NTP, dot1Q)

I have setup EVE-NG now with two vMX, 1 vQFX and 1 vEX switch.

R1 and R2 running ospf, with R1 being the GW for all NTP related traffic
R2 redistributing the default to R1 to L3-SW1 via ospv3
Configured L2-SW1 <-> L3-SW1 as trunk and running L3-SW1 as router on a stick with dot1q tagging for both the vlans (20 and 30).
Came to know that OSPV3 does not distribute V4 by default when you add an interface in an area
- You have to explicitly enable V4 using the the realm command
- set protocols ospfv3 realm ipv4-unicast area 0 interface <intf_name>

dot1q on L3-SW1

set interfaces <if_name> vlan-tagging
set interfaces <if_name> unit <id> family inet <v4_address>
set interfaces <if_name> unit <id> vlan-id <vlan_id>

dot1q on L2-SW1

# First setup the vlan name and id
set vlans <vlan_name> vlan-d <id>

# For the ports pointing to the hosts
set interfaces <if_name> unit <id> family ethernet-switching interface-mode access 
set interfaces <if_name> unit <id> family ethernet-switching vlan members <vlan_name> 

# then setup the trunk port
set interfaces <if_name> unit <id> family ethernet-switching interface-mode trunk
set interfaces <if_name> unit <id> family ethernet-switching vlan members [<vlan_name> <vlan_name>]

Really basic stuff, I am slowly getting back to my Networking roots. Enjoying it with my own solid bare-metal EVE-NG.
