Ahh, the difference is you are using VRRP-E, while I was using VRRP.

Well, tried that too:
telnet at CER2024(config)#vlan 1000
telnet at CER2024(config-vlan-1000)#unt e 1/10
telnet at CER2024(config-vlan-1000)#router-interface ve 100
telnet at CER2024(config-vlan-1000)#int ve 100
telnet at CER2024(config-vif-100)#ip addr 10.0.0.1/24
telnet at CER2024(config-vif-100)#ip addr 10.0.1.1/24
telnet at CER2024(config-vif-100)#ip vrrp-e vrid 100
telnet at CER2024(config-vif-100-vrid-100)#backup pr 50
telnet at CER2024(config-vif-100-vrid-100)#ip-address 10.0.0.2
telnet at CER2024(config-vif-100-vrid-100)#ip-address 10.0.1.2
error - cannot configure more than 1 ip-addresses per vrid
(CER running 5.0.00)
telnet at FESX624(config-vlan-1000)#unt e 15

It must be one of those things that "works on a VE" but "not on a physical
interface". My example config came from a FESX running 7.x.

Hi,
On a CER2024/5.0.00 or a FESX running whatever firmware this is not allowed:
(config-if-e1000-1/10-vrid-1)#ip-address 10.0.0.2
(config-if-e1000-1/10-vrid-1)#ip-address 10.0.1.2
error - cannot configure more than 1 ip-addresses per vrid
We work around this by having one IP per VRID.

I tried it on a Foundry switch and it seems to take it. The config looks
like this:
router vrrp
interface ve 1
ip address 192.168.1.1 255.255.255.0
ip address 192.168.2.1 255.255.255.0
ip vrrp vrid 1
owner
ip-address 192.168.1.1
ip-address 192.168.2.1
activate
FCX648SHPOE Router(config)#show ip vrrp
Total number of VRRP routers defined: 1
Interface ethernet v1
auth-type no authentication
VRID 1
state initialize
administrative-status enabled
mode owner
priority 255
current priority 255
hello-interval 1000 msec
ip-address 192.168.1.1 192.168.2.1
virtual mac address 0000.5e00.0101
advertise backup: disabled

Hi Everyone,
I just looked at what I put down in the example and realized it was
totally wrong. Should be:
interface ve 100
ip address 192.168.1.1 255.255.255.224
ip address 192.168.2.1 255.255.255.254
ip vrrp vrid 100
ip-address 192.168.1.1
ip-address 192.168.2.1
Anyone have any thoughts on this?
