[SBR] Configuring SIGTRAN link fails with error indicating address is not available

Article ID: KB27949 KB Last Updated: 04 Mar 2017Version: 2.0
Summary:

This article discusses a scenario in which, while attempting to configure a link for SIGTRAN communication, the CREATE-M3UA-SLK command fails with an error stating the IP address does not belong to any customer edge (CE) device. The Omni software will accept addresses that are resolved to the hostname in the hosts file by checking the ipnodes file located under the /etc/inet/ directory.

Symptoms:

When attempting to configure a link for SIGTRAN communication, the CREATE-M3UA-SLK command fails with an error stating the IP address does not belong to any CE device. After verifying that the address is configured using an ifconfig command, we attempt to configure the link using the MML command:

CREATE-M3UA-SLK:SLK=SLK0,LSET=LS0,LADDR=10.17.14.188,RADDR=10.17.14.162,MODE=CONNECT,RPORT=2905,LPORT=2009

This returns the following error:

M DENY
IDNV
Local IP address (LADDR) does not belong to any CE

This address exists on the server, but Omni cannot see it.  Why is this happening?

Cause:

 The /etc/hosts or /etc/inet/ipnodes file could be misconfigured.  Ensure that the address you are using resolves to the name returned with a uname -n command.

Solution:
 The Omni software will accept addresses that are resolved to the hostname in the hosts file by checking the ipnodes file located under the /etc/inet/ directory.

  1. Issue a uname -n command to see the hostname of the server:


  2. trident# uname -n
    trident

  3. Ensure the /etc/hosts file resolves this name to the intended address:

  4. trident# vi /etc/hosts
    "/etc/hosts" 8 lines, 156 characters
    "ipnodes" [Read only] 7 lines, 127 characters
    #
    # Internet host table
    #
    ::1 localhost
    127.0.0.1 localhost
    10.17.14.188 trident loghost


  5. Check to see that the ipnodes is a symbolic link to the /etc/hosts file:

trident# ls -l /etc/inet/ipnodes
lrwxrwxrwx 1 root root 7 Mar 12 2010 /etc/inet/ipnodes -> ./hosts
