xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch Web UI Reference Guide Click the VRRP Authentication Settings, as shown below: Figure 5-1067 VRRP Authentication Settings Window Click the Edit button to re-configure a specific entry listed. Figure 5-1078 VRRP Authentication Settings Edit Window The fields that can be configured are described below: Parameter Description Authentication Type Specifies the VRRP's authentication type. Options to choose from are None, Simple and IP. None - Selecting this parameter indicates that VRRP protocol exchanges will not be authenticated. Simple - Selecting this parameter will require the user to set a simple password in the Authentication Data field for comparing VRRP message packets received by a router. If the two passwords are not exactly the same, the packet will be dropped. IP - Selecting this parameter will require the user to set an IP for authentication in comparing VRRP messages received by the router. If the two values are inconsistent, the packet will be dropped. Authentication Data Specifies the authentication data used in the Simple and IP authentication algorithm. This entry must be consistent with all routers participating in the same IP interface. Simple - Simple will require the user to enter an alphanumeric string of no more than eight characters to identify VRRP packets received by a router. IP - IP will require the user to enter an alphanumeric string of no more than sixteen characters to identify VRRP packets received by a router. Click the Apply button to accept the changes made. BGP (EI Mode Only) The Switch supports Border Gateway Protocol (BGP), a layer 3 Unicast routing protocol that maintains a table of IP networks or "prefixes" which designate network reachability among autonomous systems. BGP makes routing decisions based on path, network policies, and/or rule sets. 231
