VRRP Configuration Example 1
Figure 5.4 VRRP Configuration Example
Case#1
One main router on IP subnet 20.20.20.0, such as a P333R, P460 or any router that
supports VRRP, and a redundant router. You can configure more backup routers.
• The P460 itself must have an interface on the IP subnetwork, for example,
20.20.20.2
• Configure all the routers under the same VRID, for example, 1
You must configure the routers per VLAN.
• Because of the P460 design, this VRID must not be used in the network, even in
a different VLAN
• By the end of the routers configuration, and when the network is up, the main
router for each L3 session will be elected.
• Its own IP interface is configured as DG on the stations
— It has the highest priority. You can configure this parameter
— It has the highest IP address in case of non-existence of any of the previous
cases
• The Main router adverstises a six-byte Virtual MAC address in the format
