Brocade Communications Systems ICX 7250 series User Manual

The following example shows the conguration of accept mode on an IPv6 Backup router.
Brocade(config)# interface ve 3
Brocade(config-vif-3)# ipv6 vrrp vrid 2
Brocade(config-vif-3-vrid-2)# backup
Brocade(config-vif-3-vrid-2)# advertise backup
Brocade(config-vif-3-vrid-2)# ipv6-address 2001:DB8::1
Brocade(config-vif-3-vrid-2)# accept-mode
Brocade(config-vif-3-vrid-2)# activate
Conguration considerations for IPv6 VRRP and IPv6 VRRP-E support on
Brocade devices
Consider the following when enabling IPv6 VRRP mode and IPv6 VRRP-E mode on Brocade devices:
• You can congure only one protocol (Layer 3 VSRP, VRRP, or VRRP-E) on a router at a single time. However, VRRP or VRRP-
E can be congured with IPv4 and IPv6 concurrently on a router.
• Scale timer conguration does not aect timer values, nor does it scale timer values for virtual routers congured with sub-
second time values for IPv6 VRRP and IPv4 VRRP modes.
• Abdication of a VRRP Owner router in an IPv6 environment is not supported. Abdication of an Owner router is a Brocade-
specic enhancement to VRRP. Abdication of an Owner router is possible by changing the Owner’s priority, or by conguring
track ports for an Owner router.
– For IPv6 VRRP only, the tracking port conguration is not allowed if the router is congured as the VRRP Owner. This
conforms to RFC 5798.
– For the IPv6 VRRP Owner router only, the priority conguration is not allowed. The Owner router priority is always 255.
This conforms to RFC 5798.
• Interoperability is not supported for a VRID when VRRP routers are congured as VRRP v2 or v3.
• Brocade does not recommend reuse of the same VRID across IPv6 VRRP or IPv4 VRRP or in the same broadcast domain.
• There is no specied restriction for conguring VRRP or VRRP-E instances if they are within the maximum VRID range.
Basic VRRP-E parameter
conguration
The following sections describe the conguration of the parameters specic to IPv4 and IPv6 VRRP-E.
Conguration rules for VRRP-E
Consider the following rules when conguring VRRP-E:
• The interfaces of all routers in a VRID must be in the same IP subnet.
• The IP address associated with the VRID cannot be congured on any of the Layer 3 switches.
• The Hello interval must be set to the same value with in the same VRID.
• The dead interval must be set to the same value with in the same VRID.
• The track priority for a VRID must be lower than the VRRP-E priority.
