CUE Unreachable outside the gateway

[Mounes Yaseen]

Hi all ,

We have a connectivity problem with our CUE, we installed a new ISM Module in our 2911 router, and basically the CUE is reachable from the router, but it's unpingable anywhere outside the router, we followed the instructions advised by Cisco exactly, but till this moment we are unable to reach it, noting that we have ZBF configured and we are able to ping everything in VLAN 14 which is the voice vlan except the CUE,  below is a snap of the config and couple of show commands we have typed on the router :

IIAB-Irb-Husun-R1#service-module isM 0/0 status
Service Module is Cisco ISM0/0
Service Module supports session via TTY line 131
Service Module is in Steady state
Service Module heartbeat-reset is enabled
Getting status from the Service Module, please wait..

any idea what is missing here ?

Thanks in advance.

Hi Mounes

Can you try the following

1- On global configuration

router(config)#ip routing

2-Try the following

Created loopback interface

interface Loopback0

ip address 10.3.3.1 255.255.255.0

end

interface ISM0/0

ip unnumbered Loopback0

service-module ip address 10.3.3.3 255.255.255.0

service-module ip default-gateway 10.3.3.1

end

Updated the IP ROUTE command

ip route 10.3.3.3 255.255.255.255 ISM0/0

Thanks

Please rate all useful information

Hi Islam ,

1- Routing is already enabled and we have eigrp running in our environment.

2- Attaching the ISM interface to the loopback is pretty difficult to configure since we have to make a huge changes on the CUCM and the dial plans on the CME.

Thanks.

Hi Mounes,

Could you elaborate "but it's unpingable anywhere outside the router" from  where are you trying to ping it  ?

Hello Kevin ,

I'm trying to reach the CUE from my PC on the LAN, i'm connected to the switch directly which is connected to the voice gateway via a trunk connection and the setup is basically a Router on stick, and i can see the IP Phones in VLAN 14 from my PC where i'm in VLAN 12, so i guess the routing should be ok, from the voice gateway i can login to the CUE and configure what i want, but inside the CUE, i can only ping the gateway and nothing else, even though CUE supposed to be a member in VLAN 14, but i cannot ping it.

I was thinking that ZBF maybe the cause, but since I can reache the IP Phones and ping it without any issues, CUE should be the same.

Thanks.

Hi Mounes,

I believe it is a issue of zone-member security.

Try using a different interface instead of the gig, if its not in production yet.

Let me know how it works out.

Rate the post accordingly.

Kevin

Thanks Kevin, you got it, i missed putting the ISM interface inside the zone along with Phones zone, the issue now is fixed.
