CCNA 2 v7.0 Final - What Protocol
HSRP (Hot Standby Router Protocol)
This is exclusive to Cisco and allows a default router address to be configured to be used in the event that the primary router fails. defines a group of routers, one of them defined as active and another one as standby
EtherChannel
multiple Ethernet links combined to form a single load-balancing link
DTP (Dynamic Trunk Protocol)
when you connect a switch, it automatically has access to all vlans as a trunk link to make network connectivity easy manages trunk negotiations between switches
STP (Spanning Tree Protocol)
A Layer 2 protocol that is used for routing and prevents looping by adopting a dynamic routing method.
VTP (VLAN Trunking Protocol)
Cisco's protocol for exchanging VLAN information over trunks. allows one switch on a network to centrally manage all VLANs. requires switches to be in server mode or client mode
