FLS648, VRRP and VE's

I'm attempting to configure two FLS648 switches to use VRRP for failover. I believe the switches are base layer 3, and therefore do not support use of VRRP Extended.

I can ping the vrrp address when router 1 has it, but if I make router 1 the backup I can no longer ping the vrrp address. I made sure that router 2 is the new vrrp master.

Router 1 Configuration

!

vlan 200
untagged ethernet 0/1/30 
!
interface ethernet 0/1/30
 ip address 192.168.201.1/24
 ip vrrp vrid 200
 owner
 ip-address 192.168.201.1
 activate

Router 2 Configuration

vlan 200
untagged ethernet 0/1/30 
!
!
interface ethernet 0/1/30
 ip address 192.168.201.2/24
 ip vrrp vrid 200
 backup 
 ip-address 192.168.201.1
 activate

Also, is there a limitation that prevents vrrp from working work when i put the same configuration on a virtual interface (VE)?

Re: FLS648, VRRP and VE's

This is normal for VRRP as per the standard.

Only VRRP-E (Brocade own protocol) will allow the ping to work even in

failover.

When a Backup router takes over forwarding responsibilities from a failed Master router, the Backup forwards traffic addressed to the VRID MAC address, which the host believes is the MAC address of the router interface for its default gateway. However, the Backup cannot reply to IP pings sent to the IP address(es) associated with the VRID. Because the IP address(es) are owned by the Owner, if the Owner is unavailable, the IP addresses are unavailable as packet destinations.

And yes it cannot be on a VE - must be on the interface.

We believed what you've stated to be the case, but were unable to find confirmation of it in the FLS648 documentation. Thanks very much for your help.

Shouldn't your IP for the port be different then your standby?

!
interface ethernet 0/1/30
ip address 192.168.201.1/24
ip vrrp vrid 200
owner
ip-address 192.168.201.1
activate
CMD

Re: FLS648, VRRP and VE's

Please take a look at the attached document regarding VRRP and VRRP-E differences. This screen shot is from a Brocade training PPT.  Not being able to PING the virtual IP when the owner is down is normal operation.

Hope this helps.
