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)?

This is normal for VRRP as per the standard.
Only VRRP-E (Brocade own protocol) will allow the ping to work even in
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.

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.
