L3 Switching: HSRP Configuration

Описание:

In this video, Jeremy Cioara explains configuring HSRP: Cisco’s protocol for keeping your gateways fault‑tolerant. Jeremy’s got four steps for configuring HSRP on your gateways — distribution‑layer, internet‑connected, or backup. With your gateways HSRP‑configured, your routers will be backed up in the event of a failure. The 300‑115 SWITCH exam may be retired, but the information remains valuable for anyone who wants to learn intermediate‑level networking skills. Understanding HSRP means knowing how and why an administrator should organize gateways into standby groups. It also means knowing how frequently gateways send a hello message, and how long it takes a neighbor to take over for a dead gateway after not receiving one. On top of all that, HSRP versions aren’t always uniform, and understanding which portion of the MAC address contains the HSRP version information can help ensure gateways stay in‑communication. Get ready for virtual IP, priority, interface tracking, preempt, and timer tuning configuration with Jeremy’s CCNP Routing/Switching video series.
