Important:
This functionality is currently supported for use with systems configured as an HA, or as a PDSN for
Simple IP, or as a GGSN. This keyword can only be issued for pools of type private or static and must be associated
with a different nexthop forwarding address and VLAN. A maximum of 256 over-lapping pools can be configured per
context and a maximum of 256 over-lapping pools can be configured per HA or simple IPPDSN. For GGSNs, the total
number of pools is limited by the number of VLANs defined but the maximum number per context is 256. Additional
network considerations and configuration outside of the system maybe required.

nw-reachability server server_name
Binds the name of a configured network reachability server to the IP pool and enables network reachability
detection for the IP pool. This takes precedence over any network reachability server settings in a subscriber
configuration.
detection for the IP pool. This takes precedence over any network reachability server settings in a subscriber
configuration.
server_name
: Specifies the name of a network reachable server that has been defined in the current context,
expressed as an alphanumeric string of 1 through 16 characters.
Important:
Also see the following commands for more information: Refer to the
policy nw-reachability-
fail
command in the HA Configuration Mode to configure the action that should be taken when network reachability
fails. Refer to the
nw-reachability server
command in this chapter to configure network reachability servers.
Refer to the
nw-reachability-server
command in the Subscriber Configuration Mode to bind a network
reachability server to a specific subscriber.
respond-icmp-echo ip_address
Pings the first IP address from overlapping IP address pools.
Important:
In order for this functionality to work, all of the pools should contain an initial IP address that can be
pinged.
resource
Specifies this IP pool as a resource pool. The IP addresses in resource pools may have IP addresses that also
exist in other resource pools. IP addresses from a resource pool should not be used for IP connectivity within
the system where the pool is defined. These IP addresses should be allocated for sessions which are L3
tunneled through the system (IP-in-IP or GRE). It is possible for resource pools in the same context to have
overlapping addresses when the terminating network elements for the L3 tunnels are in different VPNs.
Default: Disabled
Also refer to the Subscriber Configuration Mode Commands chapter for a description of the

Default: Disabled
Also refer to the Subscriber Configuration Mode Commands chapter for a description of the
l3-to-l2-
tunnel address-policy
command.
send-icmp-dest-unreachable
When enabled, this generates an ICMP destination unreachable PDU when the system receives a PDU
destined for an unused address within the pool.
Default: Disabled
destined for an unused address within the pool.
Default: Disabled
skip-nat-subscriber-ip-check
When enabled, this is configured to skip private IP address check for non-NAT pools. This can be configured
only for non-NAT pools during call-setup if NAT is enabled for the subscriber. If NAT is disabled, this value
is not considered.
Default: Disabled (subscriber IP check is done).
