[f-nsp] loopback interface as source for snmp

[Mario Apitz]

hi there,

we're using big iron 4000 switches.

i'd like to receive and address all management data for/from the router
via one defined network interface. that's why i configured a loopback
interface and defined this interfacce as source.


ip router-id 10.10.1.1
snmp-server community ..... ro
snmp-server community ..... rw
no snmp-server pw-check
snmp-server trap-source loopback 1
snmp-server host 10.10.11.25
interface loopback 1
 ip address 10.10.1.1 255.255.255.0
!
ip tftp source-interface loopback 1
ip sntp source-interface loopback 1


consequently, all snmp traps are send via loopback 1. that's fine so far.
but nonetheless, all snmpqueries, i.e. snmpwalk, from snmp managemnet
hosts are NOT answered by the loopback interface, but by the interface
of the shortest route, i.e.:

if i do a

# snmpwalk -v 1 -c public 10.10.1.1 system

i wont get an answer from 10.10.1.1 but from the interface with the
shortest route to the snmp workstation.


can anyone help? is there a way to bind the snmp answer to the loopback
interface?
thanks in advance for your help!



kind regards,
Mario Apitz
