You can configure an IP address as the VPG name. However, the IP address is not used in the operation of the VPG.
To configure an IP address for the VPG, include the gateway-address statement. This address is the local IP address on which the VPG receives Packet Gateway Control Protocol (PGCP) messages from the packet gateway controller (PGC). You should configure this address on a physical or loopback interface so that it is advertised through the routing protocols.
To configure the number of seconds before the VPG removes gates following a disconnection from the PGC, include the cleanup-timeout statement.
The PGC can request to be notified by the VPG when media inactivity exists on a PGCP gate. You can configure media inactivity detection parameters for the VPG when it monitors media traffic that is flowing through the gate.
To configure a delay before the VPG begins checking for media activity on a new gate, include the gate-inactivity-delay statement.
To configure the duration of time in between media inactivity detection checks that the VPG performs on a gate, include the gate-inactivity-duration statement. If no media packets are received between checks, the PGC is notified that there is media inactivity on the gate.
