FTOS Configuration Guide for the C-Series - Force10 Networks

To create a virtual router, use the following command in the INTERFACE mode:
Command Syntax Command Mode Purpose
vrrp-group vrid CONFIG-INT-
(slot/port)
To view the VRRP group or virtual router, use the show config command (Figure 310) in either the
INTERFACE or VRRP mode.
Figure 310 Command Example: show config in the VRRP Mode
Force10(conf-if-vrid-3)#show config
vrrp-group 3
Force10(conf-if-vrid-3)#
The show config command displays non-default values.
Virtual routers contain virtual IP addresses configured for that VRRP group, in addition to other
configuration information. A VRRP group does not transmit VRRP packets until you assign the virtual IP
address to the VRRP group.
To delete a VRRP group, use the no vrrp-group vrid command in the INTERFACE mode.
Assign virtual IP addresses
E-Series supports an unlimited number of VRRP groups, and up to 255 VRRP groups on a single interface.
C-Series supports 128 VRRP groups; the number of groups per interface varies. Virtual IP addresses can
either belong to the primary or secondary IP addresses configured on the interface on which VRRP is
enabled. You can ping all the virtual IP addresses configured on the Master VRRP router from anywhere
in the local subnet.
To activate a VRRP group on an interface (that is, the VRRP groups starts transmitting VRRP packets),
enter the VRRP mode and configure at least one virtual IP address in a VRRP group. The virtual IP address
is the IP address of virtual routers and does not include the IP address mask. You can configure up to 12
virtual IP addresses per VRRP group.
You can ping the virtual IP addresses to debug and test reachability.
The following rules apply to virtual IP addresses:
Create a virtual router for that interface with a
VRID.
The VRID will appear in the VRRP mode prompt
(CONFIG-INT- (slot/port) -VRID).
• The virtual IP addresses must belong to either the primary or secondary IP addresses configured on the
interface. Though a single VRRP group can contain virtual IP addresses belonging to multiple IP
subnets configured on the interface, Force10 recommends you configure virtual IP addresses
belonging to the same IP subnet for any one VRRP group.
