Be creative. Make dummy hosts using snmp as host check and base your
topology (parent) on that.
Nagios --> router --> link --> router --> host
To which router interface you need to assign this dummy link host is left
as an exercise for the reader.

Re: [Nagios-users] Server/Router with more than 1 interface
Hi Hugo, thank you very much for your suggestion.
Currently, I do the same thing with :
define command{
command_namecheck_interface
command_line$USER1$/check_snmp_cisco_ifstatus -H
$HOSTADDRESS$ -C $ARG1$ -i $ARG2$
}
However, is it possible to change HOST status in Status Map to "DOWN" if
one of the ip address could not be contacted ?
Best Regards,
Herman

This is one of those rare cases where host dependencies may come into
play.
But I would add the interfaces as PING service to the host or use SNMP to
check the real interface status. Something like:
# 'check_snmp_int' command definition define command{
command_namecheck_snmp_int
command_line$USER1$/check_snmp_int.pl -H $HOSTADDRESS$ -C $ARG1$
-n $ARG2$
}
Getting the proper interface names can be a daunting task with some
routers.

[Nagios-users] Server/Router with more than 1 interface
Dear all,
I have some servers and routers that have more than 1 interface, and
each interface has IP Address. I would like define a host is alive if
all of its interface ip address are available via check_ping.
So I define as following, but if I shut down the interface with ip
10.254.8.2. Nagios still think the host as alive, since Nagios just
detect the IP 10.16.20.120 as the indicator of the host. Any workaround
to make Nagios aware of both IP Addresses/IP Address ? Any suggestion
will be highly appreciated.
Thank you.
define host{
use generic-host; Name of host
template to use
host_name NAS-TMMIN-HO
alias FTP Server
address 10.16.20.120,10.254.8.2
parents HO_Core_SW
max_check_attempts 2
check_command check-host-alive
contact_groups admins
notification_interval 120
notification_optionsd,u,r
notification_period 24x7
flap_detection_enabled 1
