Configuring Vrrp: Backup Router (Router 2) - Dell Force10 S2410-01-10GE-24P Configuration Manual

Figure 17-257. Configuring a port for a VRRP Group
Force10 #config
Force10 (Config)#interface 1/0/2
Force10 (Interface 1/0/2)no shutdown
Force10 (Interface 1/0/2)#routing
Force10 (Interface 1/0/2)#ip address 192.150.2.1 255.255.255.0
Force10 (Interface 1/0/2)
4. Assign a virtual router ID (VRID) (a VRRP group ID) to the port:
Figure 17-258. Assigning Virtual Router ID to the Port Participating in the VRRP Group
Force10 (Interface 1/0/2)#ip vrrp 20
Force10 (Interface 1/0/2)
5. Specify the virtual IP address for that VRRP group. Note that the virtual IP address on port 1/0/2 is the
same as the port's actual IP address, so this router will always be the VRRP master when it is active.
When the virtual IP is the same as the physical IP of the router, the priority is automatically 255 — the
highest possible priority — so the router is automatically the master router in the VRRP group.
Force10 (Interface 1/0/2)#ip vrrp 20 ip 192.150.2.1
6. The mode keyword enables the VRRP group on the port:
Figure 17-259. Enabling a Virtual Router for a Port
Force10 (Interface 1/0/2)#ip vrrp 20 mode
Force10 (Interface 1/0/2)#exit
Force10 (Config)#

Configuring VRRP: Backup Router (Router 2)

1. As above, enable routing for Router 2. IP forwarding will then be enabled by default.
Force10 #config
Force10 (Config)#ip routing
2. VRRP is enabled by default for the router. If VRRP has been disabled, enable it:
Force10 (Config)#ip vrrp
Force10 (Config)#
3. Configure the IP address and subnet mask on the port that will participate in the VRRP group. (Router
2 must be on the same subnet as Router 1.)
Force10 #config
Force10 (Config)#interface 1/0/4
Force10 (Interface 1/0/4)#routing
Force10 (Interface 1/0/4)#ip address 192.150.2.4 255.255.255.0
