takes over the role of master router. This makes VRRP fully interoperable with every host
station.
VRRP can be activated on an interface using a single command while allowing for the
necessary fine-tuning of the many VRRP parameters. For a detailed description of VRRP, refer
to VRRP standards and published literature.
VRRP Configuration Example 1
Figure 31: VRRP Configuration Example (Case 1, Case 2)
Case#1
One main router on IP subnet 20.20.20.0 (C360 or any third-party router which supports VRRP)
and a redundant router (more backup routers may be configured)
● The C360 itself must have an interface on the IP subnet (e.g. 20.20.20.2)
● All the routers are configured under the same VRID (Virtual Router ID- e.g.1)
This configuration must be done per VLAN).
● The C360 requires that this VRID must not be used in the network (even in different VLAN)
