    VRID. To release the priority, IPSO subtracts the priority delta, a Nokia-specific parameter that you configure when you set up the VRID, from the priority to calculate an effective priority. If you configured your system correctly, the effective priority is lower than that of the backup routers and, therefore, the VRRP election protocol is triggered to select a new master.

    The range of values for priority is 1 to 254. The default setting is 100. Note In Nokia’s monitored-circuit VRRP, the master is defined as the router with the highest priority setting, although RFC 3768 specifies that the master must have a priority setting of 255.

    Routing Overview The Nokia routing subsystem, Ipsilon Scalable Routing Daemon (IPSRD), is an essential part of your firewall. IPSRD’s role is to dynamically compute paths or routes to remote networks. Routes are calculated by a routing protocol. IPSRD provides routing protocols, allows routes to be converted or redistributed between routing protocols, and, when there are multiple protocols with a route to a given destination, allows you to specify a ranking of protocols.
