  • 1.  DNS lookup not working

    I'm  new to Junos-based switching.

    I have a simply setup with name-server defined under system. I do not have any routing instances defined. I do not have any forwarding-options  set nor any firewall configuration.  I have a default gateway set. I am not using IPv6. I have one vlan defined, with id 10 and a corresponding irb 10 in l3-interface mode. I am running Junos 23.4.

    I am able to ping say 1.1.1.1, but I cannot ping google.com, for example. Here's the output I receive:-

    SWITCH032> ping google.com
    PING6(56=40+8+8 bytes) :: --> 2a00:1450:4009:820::200e
    ping: sendmsg: No route to host
    ping6: wrote google.com 16 chars, ret=-1

    What might I do to correct this issue please?

    This is defaulting to ipv6 and the routing on that lookup is not working.  

    To ping on ipv4 by name add inet to the string

    ping inet google.com

    Try "ping google.com inet" to force ipv4 pings.

    root@SW001> ping google.com inet
