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.
