Hi,
if i have a vlan (say vlan 2) that has the following setup.
interface vlan 2
ip address 10.1.1.254 255.255.255.0
ip address 10.2.1.254 255.255.255.0 secondary
ip address 10.3.1.254 255.255.255.0 secondary
ip proxy-arp
!
now, i have a number of devices in vlan 2 with the following
hosta IP ADD 10.1.1.1 mask 255.0.0.0
hostb IP ADD 10.2.1.1 mask 255.0.0.0
hostC IP ADD 10.3.1.1 mask 255.0.0.0
i have been told the masks CANNOT change for some reason.
they all need to communicate with each other which is fine and this works no problem, they now need to communicate with devices in vlan 3
so see below vlan 30 config
interface vlan 30
ip address 10.30.1.254 255.255.255.0
host in vlan 30 is say 10.30.1.1 mask 255.255.255.0 and g/w of 10.3.1.254
so i enabled proxy-arp on vlan 2 so that the router (msfc) will arp this and this works so host A,b,c in vlan 2 can ping host A in vlan 30. this all works perfect. EXCEPT, for no reason i know have every so often loss of communication between HOSTA in vlan 2 and HOSTB in vlan2, it comes and goes.
any ideas?
