Syntax
dns-pgw { context context_name | selection { topology [ weight ] | weight } }
{ default | no } dns-pgw { context | selection { topology [ weight ] | weight } }
default
Returns the command to its default value.
default dns-pgw context
: MRME will fetch the dns-client configuration from the current context.
default dns-pgw selection topology
: MRME will perform PGW selection based on the topology.
no
If previously configured, deletes the dns-pgw configuration.
context context_name
Specifies to configure the source context in which the DNS client is configured.
context_name
must be an alphanumeric string of 1 through 79 characters.
selection { topology [ weight ] | weight }
Specifies to enable/disable PGW selection based on topology and load-balancing of PGWs based on weights
from DNS.
from DNS.
Usage
Use this command to configure the source context in which the DNS client is configured, or enable/disable
PGW selection based on topology and load-balancing of PGWs, based on weights from DNS.
In case of topology-based selection, when the DNS procedure outputs a list of PGW hostnames for the APN
FQDN, MRME performs the longest suffix match and selects the PGW which is topologically closest to the
MRME/subscriber. In case of weight-based selection, if there are multiple entries with the same priority in
the list of PGW hostnames for the APN FQDN in the output from the DNS procedure, calls are distributed to
