View 1 Replies View RelatedI have a bunch of 3750x switches that each have a 10 gig routed link back to a central 4507 (loopback = 172.30.255.255).We carved up a /24 (of course, the /24 doesn't really exist except in our address tracking spreadsheet) into a bunch of /30's for routed WAN links and /32's for loopback addresses.We started on the low end for /30 subnets (ie 172.30.255.0/30, 172.30.255.4/30, etc.).We started at the high end for the /32 loopbacks (ie 172.30.255.255/32, 172.30.255.254/32, etc.)
Well, when I try pinging 172.30.255.255 from the access layer 3750x switches, the 3750x seems to be treating it as a broadcast ping where it lists each member that responds instead of the regular !!!!! response (this makes think something is odd with the 3750x). Of course, only one member responds (the core). But even the core seems to respond with the other end of the /30 instead of the actual /32 loopback (which makes me think something is odd in the core). I could have sworn that I've setup similar topologies without problems (ie, using 10.0.0.0/32, 10.255.255.255/32, etc as loopbacks) and as long as the mask is a /32, it should work.Also, I can ping/ssh to that loopback if my laptop is on a directly connected subnet. But I can't do it from any of the 3750x switches (which are also directly connected).I've double checked for overlapping subnets, but nope. I don't see any. Routing looks fine. The actual /32 is being propagated everywhere properly.
Here is my Lab Setup: 2691 is BGP nei to R4 router and they are not directly connected. 2691 and R4 are in same AS 6500. 2691 Config---router ospf 1 network 3.3.3.3 0.0.0.0 area 0 . Its advertising its loop back IP to OSPF domain.

I'm having with VSS Failover. Currently I have two 6504's setup for VSS with one connection to the sup engine (10Gig__Connection) and the other connection on the Module 3 10Gig Blade and the same setup on the other 6504.My question is: If the active 6504 has a power outage or the link on the sup engine goes down, and the standby 6504 becomes active, what happens when the Failed 6504 comes back online with a higher priority and preempt set? What happens with the 6504 that took over as Active and now eeds to go back to Standby, what's required?
What I'm seeing is once the Standby took over and became Active in order for him to go back to Standby mode it's asking for a reload to take place is this NORMAL?

My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.

View 4 Replies View RelatedI recently replaced a client's router with a Cisco RV 120W. The client employs a web-based application on an internal server that manages their business. Workers in the field use a handheld device power by WIndows Mobile to access a mobile version of the the web-based app. Data contained on the mobile app syncronizes with the server when workers choose a sync menu. Some workers perform this sync in the field, others wait till they return to the office and use the wireless provided by the router. Prior to changing the router, the synching worked fine either inside or outside the company network. The mobile app accesses the internal server via the router's public IP address. The router forwards the http requests to the internal server. But now the synching does not work internally. I assume it's because the Cisco RV 120 W does not support NAT Loopback, or I simply haven't figured out how to enable it. Does anyone know how to enable NAT Loopback on the RV 120 W so I can access the web-based app by through the router's external IP while on the private side of the LAN??
View 2 Replies View RelatedI am working with a device that does not have a physical reset button on it, and have mistakenly typed in 127.x.x.127 for it's IP. I was trying to use 172, but mistyped and didn't catch it until after I had rebooted the unit. Is there anyway that I might be able to gain access to the device. My PC is running Windows 7, but I am familiar with linux as well. I have attempted to change the loopback adapter IP to 128 on a ubuntu live disc and set my ethernet port to the subnet the device is on with no avail. (I am also using vlans on the device, but believe I have them set up correctly)the device is set to IP: 127.x.x.127 netmask 255.255.255.128. [code] I know that the last octet of 127 is the broadcast IP for the range, but have been able to address similar blunders before by forcing myself to a /24 subnet to correct that.

View 6 Replies View RelatedWe have 6 WAN routers connected through ISP MPLS cloud , we need to implement GET VPN between these WAN routers.We have 2 Key servers (1800 routers) , and the WAN routers will act as Group Members (6 GMs)
The attached configuration files are for working configuration for typical GETVPN (crypto map applied on WAN interface)
In Key server configuration , the crypto isakmp command is using the WAN interface IP address of each WAN router (172.16.x.x) , and since that the KS routers are connected to local backbone (VSS) , they should be able to reach 172.16.X.X , and therefore the subnet 172.16.X.X is advertised to the local network (check GM configuration file under eigrp - redist connected )
This is what our customer want to avoid ! they do not want 172.16.X.X to be advertised to the local network .I know It is possible in GETVPN configuration to configure ,the crypto isakmp command to use loopback address's of the WAN routers instead of the WAN IP , but in this case the crypto map must be applied to the loopback address , and this requires all traffic to be encrypted and decrypted to go through the loopback interfaces on all WAN routers .
i was wondering what is the best solution for this case , I though to use the below config on the GM's
I've got an SG300-10P switch and am trying to use it to create a testing environment for a Fiber Test set. What I would like to do is get two hosts, A & B, plugged into ports 1 and 3 on the switch, to talk to each other, but forcing the traffic to be routed through the two Combo ports 9 & 10. Please see the attached diagram.I've attempted to configure two VLAN's, 10 and 20. Vlan 10 is used for traffic between Ports 1 and 9, Vlan 20 is used for traffic between Ports 3 and 10.I don't really care whether the traffic is tagged or untagged as it passes between ports 9 and 10.
I've tried various combinations of tagged/untagged ports, PVID's, etc. As a first test I've bypassed the Fiber Test set and simply created a direct connection between ports 9 and 10. I am unable to get the traffic from Host A to Host B to get routed through ports 9 and 10 (I ping each host from the other and get no response).
I need to NAT a port range spanning from TCP and UDP 50,000 to 59,999 from inside global address 58.96.x.x on loopback2 to an inside local address of 192.168.5.5.Currently all the existing NAT translations are 1-to-1 that map inside global addresses on a wide span of Loopbacks and a Dialer Interface to inside local addresses on few subnets which are fine.I'm using an 1811 with an ADVIPSERVICESK9-M image, version 12.4(6)TS

We use several wireless (infrastructure mode) auto diagnostic tools which connect to the AP. We also have many laptops which run the diagnostic software.
We had no problems with our 1240AP. With our 1141, we cannot connect to the wireless tools if both the laptop and the tools are connected to the 1141. If I connect one to the 1240 and one to the 1141, they can see each other and work fine. IF they are both connected to the 1141, they show up as connected in the AP, they can ping each other, but the software does not communicate.

I had a sw/reset on my 6509 switch. The info in the crashinfo file pointed me to bug CSCso89550.
The workaround for this issue is to disable the gold diagnostics tool.
Why is loop-back only working on ports forwarded in the Virtual Server section and not Port Forwarding or even DMZ? I have seen a post about loop-back on the DIR-655 from a while ago that had said to disable SPI and change NAT Endpoint to independent, I have done this and loop-back still doesn't work.
