I have to overtake a given Network where so far cisco switches were used. The Problem is that so old configuration uses 3 Adresses in the same subnet on one vlan which are used as gateway from severals clients
Is where a way to configure a second (and/or third) ip Address in same subnet as the primary address on these HP switches?
Secondary IP in different subnet is no problem as far as I know, baut thats a other thing.
The Switches have ip routing and vrrp enabled.
Firmware is 14.60
TIA
Ralf
Solved! Go to Solution.

Re: Secondary ip address on 5400/3500
Sure thing. You go to configuration mode and just enter the IP addresses
configure
vlan 10
ip address 10.10.10.10/24
ip address 10.10.20.10/24
ip address 10.10.30.10/24
write memory

Re: Secondary ip address on 5400/3500
Sure - thats no Problem. But in your Example sie IPs are in different Subnets (Layer 3).
t I mean is:
10.10.10.1/24
10.10.10.3/24
10.10.10.5/24
One example, why I need this:
In History in this Subnet there were some more Routers. Some Maschines have one of these old Routerips as there Gateway and I cannot change this (old) gateway Address. So I want to overtake it on the new Router in additional, to a new Address

Re: Secondary ip address on 5400/3500
Sorry, that's a no-go. The IPs need to be on different subnets.

Re: Secondary ip address on 5400/3500
But, if you already have it, this will not work. Because you can configure only one instance of VRRP per IP address (subnet).
For one subnet in one switch you can configure VRRP instance to make switch reply to two IPs.
For example, you need 2 IPs in VLAN 100:
!
ip routing
!
router vrrp
!
vlan 100
ip address 10.0.100.1 255.255.255.0
vrrp vrid 100
backup
virtual-ip-address 10.0.100.5/24
enable
!
Now your switch will reply on 10.0.100.1 and 10.0.100.5

Re: Secondary ip address on 5400/3500
I allrady use vrrp.
The physical IP for the Backup Router is one of the Ip addresses I need as secondary.
But on the vrrp master the virtual IP has to be a real assigend.
It is a little bit unintelligible, that HP doesn't allow secondary IPs on Vlans for these layer-3 Switches.

SolutionYou can add one more IP with VRRP trick.
You can configure both switches as backup.
And assign them IPs, for example, .1 and .2.
But Virtual IP configure as .100.
One of backups became master.
This will work without owner.
You have with this trick 3 IPs :)

Re: Secondary ip address on 5400/3500
Not only for the underlaying Question.
I thought for a longer time how to give a virtual address as real virtual address similar to hsrp.
I forgot that in VRRP it is allowed to configure both as backup and handle the master with the priority.
