HSRP meaning in Networking ?
Answer: What is Hot Standby Routing Protocol mean?
In computer networking, the Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway. Version 1 of the protocol was described in RFC 2281 in 1998. Version 2 of the protocol includes improvements and supports IPv6 but there is no corresponding RFC published for this version.
The protocol establishes an association between gateways in order to achieve default gateway failover if the primary gateway becomes inaccessible. HSRP gateways send multicast hello messages to other gateways to notify them of their priorities (which gateway is preferred) and current status (active or standby).
