What else can I help you with?
If all routers on VLAN10 have the same HSRP priority which router will become the active router?
The highest IP address among the active interfaces will be used.
If we have 2 networks N1 N2 and 2 routersR1 R2 and we want to connect N1 with N2 through R1 and keep R2 as redundancy for R1. How can we apply same rules in R1 and R2 so if R1 goes downR2 takes place?
Look in to HSRP is you are using Cisco routers. I'm sure there are other router solutions out there. Each interface will need to be connected to the same vlan as the network it is connected to. For instance - R1 int. 1 and R2 int 1 would be on N1. R1 int2 and R2 int 2 would be on N2. There also might be a cool switch trick you could do that would monitor the interface - think spanning tree.... if it were to ever go down, then the other interface would come up. Many ways you can skin this cat.
What are the major features of CARP?
CARP, or the Common Address Redundancy Protocol, is designed to allow multiple hosts on the same local network to share a set of IP addresses, ensuring high availability and redundancy. Major features include the ability to configure virtual IP addresses that can be accessed by clients, load balancing among multiple routers, and failover capabilities that allow traffic to seamlessly switch to another router if one fails. CARP also provides a simple way to manage these shared addresses without requiring complex configurations. Additionally, it is an open-source alternative to similar protocols like HSRP and VRRP.
