Sh ip route of R5 Gateway of last resort is not setĬ 10.1.1. Sh ip route of R1 Gateway of last resort is not setĬ 10.1.1.1/32 is directly connected, Loopback1
When trying to ping the lo0.0 from the 10.10.10.0/24 subnet, the host ARPs for 10.10.10.1, since it should be in its Layer 2 network, but the SRX doesnt respond to this arp request (this is by design, AFAIK only Linux boxes proxy-arp to theirs device addressess anyway). The loopback address allows a network administrator to treat the local machine as if it were a remote machine. If I put IP address on the g0/0 interface of both routers then I can ping between loopback addresses but if I remove the IP addresses from the g0/0 then I cannot ping.ĭoes loopback need interface with IP address to ping one another? The SRX doesnt by default proxy arps it loopback addresses. If you are testing by using the host name, you must select the Protocol for. I can ping 127.0.0.1 successfully, which makes me suspect a hosts entry or dns entry, but I am getting lost in all the parms. For instance, if you think your Network Card is failing you can try: PING 127.0.0.1. TSO PING LOOPBACK gives me EZZ3111I Unknown host LOOPBACK and RTFM and even REDBOOKS has not helped me. Specify the loopback interface IP address or host name. Usage of loopback addresses are particularly popular with developers and anyone in IT performing network tests.
The interface has no IP address, I have just connected R1 g0/0 to R5 g0/0. To ping the loopback interface on your system to troubleshoot the problem, follow these steps: In IBM Navigator for i, expand IBM i Management > Network > All Tasks > TCP/IP Configuration and click Work with Ping. I have two routers attached directly and both of them has loopback address.
