VRRP (Virtual Router Redundancy Protocol) Configuration
Issue 2 July 2005 187
VRRP Configuration Example 1
Figure 28: 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)
●
By the end of the routers configuration, and when the network is up, the main router for
each virtual router will be elected according to this order of preference:
- The virtual router IP address is also the router's interface IP address
- It has the highest priority (you can configure this parameter)
- It has the highest IP address if the previous cases do not apply
