between the WLAN UEs and the ePDG. The
pgw-selection agent-info error-terminate
command specifies
the action to be taken during P-GW selection when the MIP6-agent-info parameter is expected but not received from the
AAA server/HSS, which is to terminate P-GW selection and reject the call. The
AAA server/HSS, which is to terminate P-GW selection and reject the call. The
dns-pgw selection topology
weight
command enables P-GW load balancing based on both topology, in which the nearest P-GW to the subscriber
is selected first, and weight, in which the P-GW is select based on a weighted average.
The
ip route
command in this example creates a route for the SWu interface between the WLAN UEs and the ePDG
and specifies the destination IP addresses that will use this route. The
ip domain-lookup
command enables domain
name lookup via DNS for the current context. The
ip name-servers
command specifies the IP address of the DNS
that the ePDG context will use for logical host name resolution. The
diameter endpoint
command specifies the
Diameter origin endpoint.
The
origin host
command specifies the origin host for the Diameter endpoint. The
peer
command specifies a peer
address for the Diameter endpoint. The
route-entry
