[Access-internal/12] routes

    Good day,

    this afternoon there was a small internet outage. during troubleshooting i also checked the routing table of my srx210.
    there i found out that every device in my network was listed on its own.

    172.17.20.139/32   *[Access-internal/12] 00:02:07
                        > to 172.17.20.254 via vlan.105
    172.17.20.140/32   *[Access-internal/12] 00:02:07
                        > to 172.17.20.254 via vlan.105
    172.17.20.143/32   *[Access-internal/12] 00:02:07
                        > to 172.17.20.254 via vlan.105
    ​

    the subnet is also listed (as i normaly expect)

    172.17.20.0/24     *[Direct/0] 00:02:11
                        > via vlan.105
    ​


    Everything works as expected. so not sure if there is any problem at all.

    during the search i found some references to dhcp/ppp.
    a few weeks ago i changed provider. i may no longer set the static ip on the interface but have to use pppoe now.
    not sure if this is the "problem"

     show interfaces pp0
    unit 0 {
        ppp-options {
            pap {
                local-name "******";
                local-password "*****"; ## SECRET-DATA
                passive;
            }
        }
        pppoe-options {
            underlying-interface pt-1/0/0.0;
            client;
        }
        family inet {
            negotiate-address;
        }
    }

    This is normal I think, and seems to be the way it is with ELS devices? We did not have this sort of  "sh route" output on our older EX4500s, but see that same behavior on the ELS QFXes which replaced them. 

    The QFX seems to list every device as a /32 entry on the subnets for which it is the gateway. 

    (Or, if it is an issue, then we have the same problem!)
