Enabling accept mode in VRRP non-Owner Master router
To configure a non-Owner Master router to respond to ping, traceroute, and Telnet packets destined
for the virtual IPv4 or IPv6 address of a VRRP cluster, use the accept-mode command in the VRRP
configuration mode.
The following example shows the configuration 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
Configuration considerations for IPv6 VRRP v3 and IPv6 VRRP-E v3
support on Brocade devices
Consider the following when enabling IPv6 VRRP v3 mode and IPv6 VRRP-E v3 mode on Brocade
devices:
You can configure only one protocol (Layer 3 VSRP, VRRP, or VRRP-E) on a router at a single time.
However, VRRP or VRRP-E can be configured with IPv4 and IPv6 concurrently on a router.
Scale timer configuration does not affect timer values, nor does it scale timer values for virtual routers
configured with sub-second time values for IPv6 VRRP and IPv4 VRRP v3 modes.
Abdication of a VRRP Owner router in an IPv6 environment is not supported. Abdication of an Owner
router is a Brocade-specific enhancement to VRRP. Abdication of an Owner router is possible by
changing the Owner’s priority, or by configuring track ports for an Owner router.
For IPv6 VRRP v3 only, the tracking port configuration is not allowed if the router is
configured as the VRRP Owner. This conforms to RFC 5798.
For the IPv6 VRRP v3 Owner router only, the priority configuration 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 configured as VRRP v2 or v3.
Brocade does not recommend to re-use the same VRID across IPv6 VRRP or IPv4 VRRP or if they
are in the same broadcast domain.
There is no specified restriction for configuring VRRP or VRRP-E instances if they are within the
maximum VRID range.
Basic VRRP-E parameter configuration
The following sections describe the configuration of the parameters specific to IPv4 and IPv6 VRRP-E.
Configuration rules for VRRP-E
Consider the following rules when configuring 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 configured on any of the Layer 3 switches.
