Otherwise the the 5.5.5.0 or 6.6.6.0 networks will never make it across to the correct router. Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 msĪlso - as a note - when using RIP, you will need to advertise both 5.5.5.0 and 192.168.1.0. Packet sent with a source address of 6.6.6.6 The loopback interface will not work for the dynamic VPN as per design. Sending 5, 100-byte ICMP Echos to 5.5.5.5, timeout is 2 seconds: Use a physical interface, instead of using the loopback interface which is a logical interface. Packet sent with a source address of 5.5.5.5 Sending 5, 100-byte ICMP Echos to 6.6.6.6, timeout is 2 seconds: Loose, Strict, Record, Timestamp, Verbose: But I am still answering the question.įill out the form & at the Extended commands choose/type Y and enter the source address Thoughts? This one seems to have stumped JTAC.OK - I know that this is over six years OLD and I know that it is probably answered 100 times elsewhere. And I can even see in my filter that counts ICMP packets that packets are getting there, but not doing anything. However nothing I can do can ping that IP. The reason to ping the loopback, is to confirm the stack is working as again this interface should be running all of the time, if it doesnt respond (and you have no firewall rules, and the interface is up), then most likely there is an failure of the IP Stack, which means the physical interfaces will not be up, and would be pointless to bring up any services. Task: RPD Unix Domain Server./var/run/rpd_serv.localĪnnouncement bits (2): 0-KRT 3-Resolve tree 1Īnd my understanding is that the "Next hope type: Discard" is correct/normal for proxy-arp's. Inet.0: 17 destinations, 18 routes (17 active, 0 holddown, 0 hidden) And I can see that it installs the route for it: Which seems pretty simple and straight forward. However I now have static NAT issues that aren't resolved. Of course! That made perfect sense and fixed the locally attached IP's. This is from SRX210 with JUNOS 11.4, I don't have a SRX with 12.1 code but expect it to behave the same. + = Active Route, - = Last Active, * = Both Inet.0: 11 destinations, 12 routes (11 active, 0 holddown, 0 hidden) There is a workaround - You need to spell /24 only once as show configuration interfaces lo0Īnd the result show route 198.97.232.0/24 What you need to do is cancel that pointing from the hostname to the loopback address: in Linux edit the /etc/hosts and comment out the line 127.0.0.1 YOURHOSTNAME. 1 belong - "do they belong to me or are they directly connected?" Thats probably because your hostname is pointing to the loopback address hence socket.gethostbyname (socket.gethostname ()) will yield 127.0.0.1. I think it is pretty clear - You are telling Your SRX router the following:ġ/ that all other addresses apart from 198.97.232.2 are directly connected to lo0.0Ģ/ that all other addresses apart from 198.97.232.1 are directly connected to lo0.0 There’s also a hostname localhost assigned to this IP address by default. We can see that the lo interface has an IP address of 127.0.0.1, with a netmask 255.0.0.0, which is equivalent to /8. It also won't show up on the interface show interfaces terse | match lo0Īm I missing something obvious about why this isn't working as I expect? The eth0 is a physical ethernet interface, and the lo is our loopback interface. It installs the correct route on the device:īut there is no /32 route for the. This however doesn't seem to be working. The interface configuration show configuration interfaces lo0 The actual /24 IP's that I advertise are bound on the loopback interface. The two interfaces peering with the ISP's have a local IP address on them that is just the peering IP. I advertise my /24, and they advertise just a 0.0.0.0 back to me. To provide availablility, I have two ISP's terminating in the device and doing BGP with them. I have an SRX550 with version 12.1X44-D20.3. Im trying to configure loopback interfaces on (2) 3560 Multilayer switches that i can ping from any computer.
