  • 1.  Internet Connection to LTE Mini PIM -- Stumped

    Posted 12-06-2023 20:11

    Greetings,

    I have an SRX 345 unit with an LTE mini-PIM card that's connected to the cellular carrier (is configured and connected.)

    I've spent (too many) hours trying to get this unit to ping 8.8.8.8 via the LTE interface, but as yet, I'm just stumped and I can't see right now what I'm missing.

    Could someone take a look at the config and tell me what I'm not seeing?  I've based some of this config off of some of the tutorials online (e.g. interface ge-0/0/1).

    Any help would be much appreciated.

    Thank you.

    Hi,

    if you want to test your lte connection.. you need to change your default route.. it is now pointing to a default behind a ge interface.  

    route 0.0.0.0/0 next-hop dl0.0 should make you be able to reach 8.8.8.8.  Disable or remove the default you have now in the config

    Thanks Marc,

    next-hop dl0.0 was my original configuration, so yes, I've tried that as well.  I'm still not getting anything back, which is why I'm so stumped.

    I'm getting full on IP address on the LTE interface, so seems like all should be working normally.  Is there another way to test the connectivity of the LTE card?

    There are a couple of how-tos out there with reference to Dual ISP WAN setup, including several within the Juniper community forum.  We're not load balancing our outbound traffic, but we do have dual ISP setup, so I thought I'd share what's currently working for us

    srx345-1> show configuration interfaces ae1 | display set
    set interfaces ae1 description "Fiber Uplink"
    set interfaces ae1 aggregated-ether-options link-speed 1g
    set interfaces ae1 aggregated-ether-options lacp active
    set interfaces ae1 unit 0 family inet address 1.1.1.2/28

    set routing-options rib-groups spectrum import-rib inet.0
    set routing-options rib-groups spectrum import-rib spectrum.inet.0
    set routing-options forwarding-table export load-balance
    
    srx345-1> ping source 1.1.1.2 4.2.2.2 count 1
    PING 4.2.2.2 (4.2.2.2): 56 data bytes
    64 bytes from 4.2.2.2: icmp_seq=0 ttl=53 time=9.340 ms
    
    --- 4.2.2.2 ping statistics ---
    1 packets transmitted, 1 packets received, 0% packet loss
    round-trip min/avg/max/stddev = 9.340/9.340/9.340/0.000 ms
    
    srx345-1> ping routing-instance spectrum source 2.2.2.2. 4.2.2.2 count 1
    PING 4.2.2.1 (4.2.2.1): 56 data bytes
    64 bytes from 4.2.2.1: icmp_seq=0 ttl=57 time=17.332 ms
    
    --- 4.2.2.1 ping statistics ---
    1 packets transmitted, 1 packets received, 0% packet loss
    round-trip min/avg/max/stddev = 17.332/17.332/17.332/0.000 ms
    

    The first couple of bits are just creating the interfaces and route setup.  The final ping examples are shown using unique routes out, you'll notice the difference in response time shows to verify different links/speeds.

    Well, turns out that I just needed to call Verizon and have them refresh the line, since all my configs were correct to begin with.
