The SBC Core supports tracing routes for specific peer IP addresses. The The To allow the Internet Control Message Protocol (ICMP) packets from different routers when the Note For the
traceroute utility provided by the GNU/Linux is utilized as a base for this functionality. This feature handles and processes the
traceroute requests from the Signaling Gateway (SG).
traceroute functionality for a peer IP address is invoked by sending a
traceroute request message to the
Traceroute module. The message contains details of the peer's IP address, which is processed by the
TRCRT/Traceroute module. This feature supports the following scenarios:
traceroute request to log the route for the blacklisted server.
traceroute request to log the route for the peer GW server.
traceroute starts, an Access Control List (ACL) entry is configured. As soon as the
traceroute output is available, this ACL entry is removed.
traceroute utility to work, a higher precedence "IP ACL rule" is created to accept ICMP traffic on the SIP Signaling port. This rule overrides any "deny-all" or "deny-ICMP" User ACL rule configured by the Administrator. This higher precedence "IP ACL rule" is created before the start of
traceroute for an endpoint, and is be removed as soon as the
traceroute is over. Thus, for the brief duration of
traceroute, the ICMP traffic to the Signaling port is allowed from any IP address, even if "deny-ICMP" or "deny-all" User ACL rules are configured in the system.
