  HSRP (Hot Standby Router Protocol) HSRP (Hot Standby Router Protocol) adalah Cisco-proprietary redundancy protocol untuk membangun toleransi kesalahan pada default gateway. HSRP menerapkan mekanisme failover transparent pada end device di dalam jaringan. Dalam hal ini user yang berada pada layer access(L2) tidak akan tergangu apabila  primary default gateway mengalami gangguan dalam hal akses.
